2018-08-30mmc: renesas-sdhi: Use priv directlyMarek Vasut
The dev_get_priv(dev) is used twice in the probe function. Replace the second invocation with priv variable. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Masahiro Yamada <yamada.masahiro@socionext.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-24mmc: tmio: move clk_enable() to each driver's probe functionMasahiro Yamada
I need to differentiate the clock handling for uniphier-sd. Move it to each driver's probe function from the tmio common code so that renesas-sdhi will not be affected. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2018-04-14mmc: tmio: Rename Matsushita to TMIOMarek Vasut
Synchronize the naming with Linux, call the common code TMIO. No functional change. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Jaehoon Chung <jh80.chung@samsung.com> Cc: Masahiro Yamada <yamada.masahiro@socionext.com>
2018-04-11mmc: renesas-sdhi: Wait after reconfiguring pinsMarek Vasut
The IP requires some time to recuperate after the IO pin properties were changed. Add a delay to assure this. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Jaehoon Chung <jh80.chung@samsung.com> Cc: Masahiro Yamada <yamada.masahiro@socionext.com>
2018-04-11mmc: renesas-sdhi: Add Renesas SDR104/HS200 tuning supportMarek Vasut
Add code for PHY tuning required for SDR104/HS200 support on Renesas RCar. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Jaehoon Chung <jh80.chung@samsung.com> Cc: Masahiro Yamada <yamada.masahiro@socionext.com>
2018-04-11mmc: matsushita-common: Add Renesas RCar quirksMarek Vasut
Add a quirk to identify that the controller is Renesas RCar variant of the Matsushita SD IP and another quirk indicating it can support Renesas RCar HS200/HS400/SDR104 modes.

2018-04-11mmc: renesas-sdhi: Handle 16bit IPMarek Vasut
The Renesas RCar Gen2 chips have a mix of 32bit and 16bit variants of the IP. There is no DT property which allows discerning those, so what Linux does is it checks the size of the register area and if it is 0x100, the IP is 16bit, otherwise the IP is 32bit. Handle the distinction the same way. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Jaehoon Chung <jh80.chung@samsung.com> Cc: Masahiro Yamada <yamada.masahiro@socionext.com>
2018-04-11mmc: uniphier: Allow passing quirks to the probe functionMarek Vasut
Certain instances of the SD IP require more elaborate digging in the DT to figure out which variant of the SD IP is in use. Allow explicit passing of the quirks into the probe function.

2018-04-11mmc: uniphier: Split out SoC specific bits from the driverMarek Vasut
Factor out common code from the uniphier SD driver, change the prefix of the functions from uniphier_sd_ to matsu_sd_ and create separate renesas-sdhi.c driver. Thus far, all the code is still compiled when CONFIG_UNIPHIER_MMC is selected and there is no functional change. This patch is a preparation for further split of the SoC specific parts of the Matsushita SD driver, used both on Uniphier and R-Car.
