2009-06-17mfd: asic3: enable SD/SDIO cellPhilipp Zabel1-1/+113
This enables the ASIC3's SD/SDIO MFD cell, supported by the tmio_mmc driver. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-06-17mfd: asic3: enable DS1WM cellPhilipp Zabel1-0/+99

2009-06-17mfd: asic3: use resource_size macro instead of local variablePhilipp Zabel1-4/+2
This should make the code a little bit easier to read. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-06-17mfd: asic3: add clock handling for MFD cellsPhilipp Zabel1-0/+80
Since ASIC3 has to work on both PXA and S3C and since their struct clk implementations differ, we can't register out clocks with the clkdev mechanism (yet?). For now we have to keep clock handling internal to this driver and enable/disable the clocks via the mfd_cell->enable/disable functions.

2009-06-17mfd: asic3: add asic3_set_register common operationPhilipp Zabel1-0/+15
Used to configure single bits of the SDHWCTRL_SDCONF and EXTCF_RESET/SELECT registers needed for DS1WM, MMC/SDIO and PCMCIA functionality. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2008-11-27[ARM] remove memzero()Russell King1-3/+3
As suggested by Andrew Morton, remove memzero() - it's not supported on other architectures so use of it is a potential build breaking bug. Since the compiler optimizes memset(x,0,n) to __memzero() perfectly well, we don't miss out on the underlying benefits of memzero(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-10-16generic: sparse irqs: use irq_desc() together with dyn_array, instead of irq_desc[]Yinghai Lu1-2/+2
add CONFIG_HAVE_SPARSE_IRQ to for use condensed array. Get rid of irq_desc[] array assumptions. Preallocate 32 irq_desc, and irq_desc() will try to get more. ( No change in functionality is expected anywhere, except the odd build failure where we missed a code site or where a crossing commit itroduces new irq_desc[] usage. ) v2: according to Eric, change get_irq_desc() to irq_desc() Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

map_size was declared from the wrong place. Signed-off-by: Samuel Ortiz <sameo@openedhand.com>
2008-08-23removed unused #include <linux/version.h>'sAdrian Bunk1-1/+0
This patch lets the files using linux/version.h match the files that #include it. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-07-27[ARM] 5179/1: Replace obsolete IRQT_* and __IRQT_* values with IRQ_TYPE_*Dmitry Baryshkov1-7/+7
IRQT_* and __IRQT_* were obsoleted long ago by patch [3692/1]. Remove them completely.

2008-07-26asic3: platform_get_irq() may return signed unnoticedRoel Kluin1-3/+5
asic->irq_nr is unsigned. platform_get_irq() may return signed unnoticed Signed-off-by: Roel Kluin <12o3l@tiscali.nl> Cc: Joe Perches <joe@perches.com> Acked-by: Samuel Ortiz <sameo@openedhand.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-07-20mfd: let asic3 use mem resource instead of bus_shiftPhilipp Zabel1-6/+5
The bus_shift parameter in platform_data is not needed as we can tell the driver with the IOMEM_RESOURCE whether the ASIC is located on a 16bit or 32bit memory bus. The htc-egpio driver uses a more descriptive bus_width parameter, but for drivers where the register map size fixed, we don't even need this.

2008-07-20mfd: fix the asic3 irq demux codePhilipp Zabel1-1/+1
Wrong irq numbers were given to desc->handle_irq, which on some devices caused endless loops (asic3_irq_demux calling itself, basically).

2008-07-20mfd: Use uppercase only for asic3 macros and definesSamuel Ortiz1-44/+44
Let's be consistent and use uppercase only, for both macro and defines. Signed-off-by: Samuel Ortiz <sameo@openedhand.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2008-07-20mfd: use dev_* macros for asic3 debuggingSamuel Ortiz1-14/+13
We replace the various printks, and use the dev_* macros instead. Signed-off-by: Samuel Ortiz <sameo@openedhand.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2008-07-20mfd: New asic3 gpio configuration codeSamuel Ortiz1-56/+43
The ASIC3 GPIO configuration code is a bit obscure and hardly readable. This patch changes it so that it is now more readable and understandable, by being more explicit. Signed-off-by: Samuel Ortiz <sameo@openedhand.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2008-07-20mfd: asic3 children platform data removalSamuel Ortiz1-8/+0
Platform devices should be dynamically allocated, and each supported device should have its own platform data. For now we just remove this buggy code. Signed-off-by: Samuel Ortiz <sameo@openedhand.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2008-07-20mfd: asic3 gpiolib supportSamuel Ortiz1-71/+153
ASIC3 is, among other things, a GPIO extender. We should thus have it supporting the current gpiolib API. Signed-off-by: Samuel Ortiz <sameo@openedhand.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

2008-02-07ASIC3 driverSamuel Ortiz1-0/+588
This is a patch for the Compaq ASIC3 multi function chip, found in many PDAs (iPAQs, HTCs...). It is a simplified version of Paul Sokolovsky's first proposal [1]. With this code, it is basically a GPIO and IRQ expander. My plan is to add more features once this patch gets reviewed and accepted.
