2016-05-02mmc: tmio: remove now unneeded seperate irq handlersWolfram Sang2-32/+2
We removed installation of separate handlers previously, so we can also remove the separate handlers. Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

There is no user left in the kernel, so this code can be removed. (Legacy, non-DT sh_mobile boards have been removed a while ago.) The diff looks more complicated than it is: The if-block for multiplexed isr is now the main code path, the rest is removed.

2016-05-02mmc: sdhci: Remove SDHCI_SDR104_NEEDS_TUNINGAdrian Hunter2-7/+1
SDHCI_SDR104_NEEDS_TUNING was originally named SDHCI_HS200_NEEDS_TUNING and was added in commit 069c9f142822 ("mmc: host: Adds support for eMMC 4.5 HS200 mode"). That commit conflated SDHCI_SDR50_NEEDS_TUNING and SDHCI_HS200_NEEDS_TUNING due to what appears to be misplaced parentheses. Commit 156e14b126ff ("mmc: sdhci: fix caps2 for HS200") made HS200 configuration equivalent to SDR104 configuration, renaming SDHCI_HS200_NEEDS_TUNING to SDHCI_SDR104_NEEDS_TUNING despite tuning for HS200 now being non-optional. The mix-up with SDHCI_SDR50_NEEDS_TUNING remained and became more obvious after commit 4b6f37d3a379 ("mmc: sdhci: clean up sdhci_execute_tuning() decision") where the author noted the patch was "reflecting what the original code was doing, it shows that it may not be what the author actually intended." The way the code is currently written, SDHCI_SDR104_NEEDS_TUNING causes tuning to be done always for SDR50 mode if SDR104 mode is also supported by the host controller. That makes no sense because we already have capabilities bit SDHCI_USE_SDR50_TUNING and corresponding flag SDHCI_SDR50_NEEDS_TUNING for that purpose. Given the dubious origins of SDHCI_SDR104_NEEDS_TUNING, it seems reasonable to remove it. The benefit being SDR50 mode will now not un-nessessarily do tuning.

2016-05-02mmc: sdhci-pltfm: call platform_get_irq() before sdhci_alloc_host()Masahiro Yamada1-11/+9
Swap the call order of sdhci_alloc_host() and platform_get_irq(). It makes sdhci_alloc_host() the last function that can fail in the sdhci_pltfm_init().

2016-05-02mmc: sdhci-pltfm: drop error message for too small MMIO resource sizeMasahiro Yamada1-3/+0
The requirement resource_size >= 0x100 may not necessarily be reasonable; for example, sdhci-dove appears to sidestep some registers in sdhci_dove_readw(). Moreover, current code displays an error message for too small resource size, but still moves forward. Every DT should be responsible for describing its properties correctly, so lets's remove this error message from the common framework.

2016-05-02mmc: pwrseq: convert to proper platform deviceSrinivas Kandagatla6-129/+177
simple-pwrseq and emmc-pwrseq drivers rely on platform_device structure from of_find_device_by_node(), this works mostly. But, as there is no driver associated with this devices, cases like default/init pinctrl setup would never be performed by pwrseq. This becomes problem when the gpios used in pwrseq require pinctrl setup. Currently most of the common pinctrl setup is done in drivers/base/pinctrl.c by pinctrl_bind_pins(). There are two ways to solve this issue on either convert pwrseq drivers to a proper platform drivers or copy the exact code from pcintrl_bind_pins(). I prefer converting pwrseq to proper drivers so that other cases like setting up clks/parents from dt would also be possible.

2016-05-02mmc: sdhci-of-at91: Implement specific ->set_clock() functionLudovic Desroches1-2/+46
Disabling the internal clock while configuring the SD card clock can lead to internal clock stabilization issue and/or unexpected switch to the base clock when using presets. A quirk SDHCI_QUIRK2_NEED_DELAY_AFTER_INT_CLK_RST was introduced to fix these bugs. The cause was assumed to be a too long internal re-synchronisation but it seems in some cases the delay (even if longer) doesn't fix this bug. The safest workaround is to not disable/enable the internal clock during the SD card clock configuration.

2016-05-02mmc: core: Do regular power cycle when lacking eMMC HW reset supportGwendal Grignou2-15/+14
The eMMC HW reset may be implemented either via the host ops ->hw_reset() callback or through DT and the eMMC pwrseq. Additionally some eMMC cards don't support HW reset. To allow a reset to be done for the different combinations of mmc hosts and eMMC/MMC cards, let's implement a fallback via trying a regular power cycle. This improves the mmc block layer retry mechanism of failing I/O requests.
