2007-10-18PM: Move definition of struct pm_ops to suspend.hRafael J. Wysocki1-0/+2
Move the definition of 'struct pm_ops' and related functions from <linux/pm.h> to <linux/suspend.h> . There are, at least, the following reasons to do that: * 'struct pm_ops' is specifically related to suspend and not to the power management in general. * As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it causes the entire kernel to be recompiled, which is unnecessary and annoying. * Some suspend-related features are already defined in <linux/suspend.h>, so it is logical to move the definition of 'struct pm_ops' into there. * 'struct hibernation_ops', being the hibernation-related counterpart of 'struct pm_ops', is defined in <linux/suspend.h> .

2007-10-16pxafb: Add support for other palette formatsHans J. Koch2-1/+17
This patch adds support for the other three palette formats possible with the PXA LCD controller. This is required on boards where an LCD is connected with all its 18 bits. With this patch, it's possible to use an 8-bit mode with 18-bit palette entries. This used to be possible in 2.4 kernels but disappeared in 2.6. With current kernels, you can only get wrong colours out of an LCD connected this way. Users can choose the palette format by doing something like this in their board definition: static struct pxafb_mach_info my_fb_info = { [...] .lccr3 = LCCR3_OutEnH | LCCR3_PixFlEdg | LCCR3_PDFOR_3, .lccr4 = LCCR4_PAL_FOR_2, [...] }; Signed-off-by: Hans J.

2007-10-15[ARM] pxa: Avoid pxa_gpio_mode() in gpio_direction_{in,out}put()Russell King1-10/+2
pxa_gpio_mode() is a universal call that fiddles with the GAFR (gpio alternate function register.) GAFR does not exist on PXA3 CPUs, but instead the alternate functions are controlled via the MFP support code. Platforms are expected to configure the MFP according to their needs in their platform support code rather than drivers. We extend this idea to the GAFR, and make the gpio_direction_*() functions purely operate on the GPIO level. This means platform support code is entirely responsible for configuring the GPIOs alternate functions on all PXA CPU types. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-10-12[ARM] 4559/1: pxa: make PXA_LAST_GPIO a run-time variableeric miao1-6/+0
This definition produces processor specific code in generic function pxa_gpio_mode(), thus creating inconsistencies for support of pxa25x and pxa27x in a single zImage. As David Brownell suggests, make it a run-time variable and initialize at run-time according to the number of GPIOs on the processor. For now the initialization happens in pxa_init_irq_gpio(), since there is already a parameter for that, besides, this is and MUST be earlier than any subsequent calls to pxa_gpio_mode().

2007-07-12[ARM] 4451/1: pxa: make dma.c generic and remove cpu specific dma codeEric Miao1-20/+2
Since the number of dma channels varies between pxa25x and pxa27x, it introduces some specific code in dma.c. This patch moves the specific code to pxa25x.c and pxa27x.c and makes dma.c more generic. 1. add pxa_init_dma() for dma initialization, the number of channels are passed in by the argument 2. add a "prio" field to the "struct pxa_dma_channel" for the channel priority, and is initialized in pxa_init_dma() 3. use a general priority comparison with the channels "prio" field so to remove the processor specific pxa_for_each_dma_prio macro, this is not lightning fast as the original one, but it is acceptable as it happens when requesting dma, which is usually not so performance critical Signed-off-by: eric miao <eric.miao@marvell.com> Acked-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-04-21[ARM] 4304/1: removes the unnecessary bit number from CKENnn_XXXXEric Miao1-29/+29
This patch removes the unnecessary bit number from CKENnn_XXXX definitions for PXA, so that CKEN0_PWM0 --> CKEN_PWM0 CKEN1_PWM1 --> CKEN_PWM1 ... CKEN24_CAMERA --> CKEN_CAMERA The reasons for the change of these defitions are: 1. they do not scale - they are currently valid for pxa2xx, but definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera instead of bit 24 2. they are unnecessary - the peripheral name within the definition has already announced its usage, we don't need those bit numbers to know which peripheral we are going to enable/disable clock for 3. they are inconvenient - think about this: a driver programmer for pxa has to remember which bit in the CKEN register to turn on/off Another change in the patch is to make the definitions equal to its clock bit index, so that #define CKEN_CAMERA (24) instead of #define CKEN_CAMERA (1 << 24) this change, however, will add a run-time bit shift operation in pxa_set_cken(), but the benefit of this change is that it scales when bit index exceeds 32, e.g., pxa3xx has two registers CKENA and CKENB, totally 64 bit for this, suppose CAMERA clock enabling bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10) and so that pxa_set_cken() need minimum change to adapt to that.

2007-04-21[ARM] 4246/1: i2c-pxa: add adapter class to platform specific dataMatej Kenda1-0/+1
Reposted patch for kernel 2.6.21-rc2. The driver i2c-pxa doesn't set the class member in i2c_adapter, which is used to register the I2C adapter. The hwmon (sensors) drivers (e.g. adm1021) that are connected to a i2c-pxa adapter don't attach because they expect that the adapter supports class I2C_CLASS_HWMON. This patch adds functionality to allow platforms to set the class and pass it as platform_data to the i2c-pxa driver. Sample usage in platform code: static struct i2c_pxa_platform_data my_i2c_platform_data = { .class = I2C_CLASS_HWMON }; static void __init my_platform_init(void) { (void) platform_add_devices(devices, ARRAY_SIZE(devices)); pxa_set_i2c_info(&my_i2c_platform_data); } Signed-off-by: Matej Kenda <matej.kenda@hermes-softlab.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

It has been reported by Julian Deng that configuring the pxa27x i2c SCL line as output generates a short negative pulse on it during the call to pxa_gpio_mode(GPIO117_I2CSCL_MD); as it first switches it to output and then configures it for the alternate function. The SCL line is in fact bidirectional and can also be configured as 117 | GPIO_ALT_FN_1_IN, in which case the pulse is not generated. This is exactly what this patch does.

2007-03-16[PATCH] gpio_direction_output() needs an initial valueDavid Brownell1-2/+2
It's been pointed out that output GPIOs should have an initial value, to avoid signal glitching ... among other things, it can be some time before a driver is ready. This patch corrects that oversight, fixing - documentation - platforms supporting the GPIO interface - users of that call (just one for now, others are pending) There's only one user of this call for now since most platforms are still using non-generic GPIO setup code, which in most cases already couples the initial value with its "set output mode" request. Note that most platforms are clear about the hardware letting the output value be set before the pin direction is changed, but the s3c241x docs are vague on that topic ... so those chips might not avoid the glitches.

The Lubbock platform uses both a PXA25x and a SA1111 at the same time. Both chips have the same "Serial Audio Controller" registers although the SA1111 one is never expected to be used in preference to the PXA25x one. So let's disable the SA1111 defines whenever compilation is for a PXA architecture and make the PXA defines always defined. This removes a bunch of "already defined" warnings as well since the current hack to prevent them depended on include ordering which wasn't always right.

This patch renames pxa_gpio_set/get functions defined in drivers/usb/gadget/pxa2xx_udc.h to udc_gpio_set/get. These functions are moved from drivers/usb/gadget/pxa2xx_udc.h to include/asm-arm/arch-pxa2xx/udc.h Creates new functions: udc_gpio_to_irq, udc_gpio_init_vbus, udc_gpio_init_pullup in include/asm-arm/arch-pxa2xx/udc.h. These functions are used in drivers/usb/gadget/pxa2xx_udc.c instead of direct low-level (pxa2xx only) functions. Creates all these udc_gpio_* functions in include/asm-arm/arch-ixp4xx/udc.h. This implementation has no real code because ixp4xx doesn't use vbus - only vbus uses all these gpio functions (and because ixp4xx misses any function which converts number of gpio pin into it's irq).

Of the possible SSP frame formats (FRF bits in SSCR0), only SSCR0_PSP is defined. Other possible formats are Motorola SPI (0<<4), TI SSP (1<<4) and Microwire (2<<4). Attached patch adds a definition SSCR0_TISSP. This mode is used for the sound codec attached to the PXA272 SSP1 of some HTC PDA phones.

2007-01-02[ARM] 4080/1: Fix for the SSCR0_SlotsPerFrm macroPhilipp Zabel1-1/+1
The SSCR0_SlotsPerFrm macro writes a 3-bit value to bits [2:0], while the correct location of FRDC in SSCR0 is at bits [26:24]. This patch adds the missing "<< 24". Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-12-10[PATCH] spi: stabilize PIO mode transfers on PXA2xx systemsStephen Street1-4/+1
Stabilize PIO mode transfers against a range of word sizes and FIFO thresholds and fixes word size setup/override issues. 1) 16 and 32 bit DMA/PIO transfers broken due to timing differences. 2) Potential for bad transfer counts due to transfer size assumptions. 3) Setup function broken is multiple ways. 4) Per transfer bit_per_word changes break DMA setup in pump_tranfers. 5) False positive timeout are not errors. 6) Changes in pxa2xx_spi_chip not effective in calls to setup. 7) Timeout scaling wrong for PXA255 NSSP. 8) Driver leaks memory while busy during unloading. Known issues: SPI_CS_HIGH and SPI_LSB_FIRST settings in struct spi_device are not handled. Testing: This patch has been test against the "random length, random bits/word, random data (verified on loopback) and stepped baud rate by octaves (3.6MHz to 115kHz)" test. It is robust in PIO mode, using any combination of tx and rx thresholds, and also in DMA mode (which internally computes the thresholds). Much thanks to Ned Forrester for exhaustive reviews, fixes and testing. The driver is substantially better for his efforts.

2006-11-30[ARM] Clean up discontigmem supportRussell King1-33/+3
Most architectures have fairly simple discontiguous memory - a simple set of successive regions each containing some memory. These can be described simply as a log2 of their maximum size, along with the base address of the first region and the number of regions. The base address is already described by PHYS_PFN_OFFSET, and the number of regions via the MAX_NUMNODES and the number of online nodes. If we then supply the log2 of their maximum size, all the other discontigmem macros can move into generic code. There is one exception: lh7a40x seems to have a more complicated setup; this is left alone. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
