2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2020-01-16mmc: add mmc and sd support for MT7622Sam Shih
This patch add mmc and sd support for Mediatek MT7622 SoCs Signed-off-by: Sam Shih <sam.shih@mediatek.com> Reviewed-by: Ryder Lee <ryder.lee@mediatek.com>
2020-01-16mmc: mtk-sd: fix hang when data read quicklymingming lee
For CMD21 tuning data, the 128/64 bytes data may coming in very short time, before msdc_start_data(), the read data has already come, in this case, clear MSDC_INT will cause the interrupt disappear and lead to the thread hang. the solution is just clear all interrupts before command was sent.

2020-01-16mmc: mtk-sd: add support for MediaTek MT8512/MT8110 SoCsmingming lee
This patch adds mmc support for MediaTek MT8512/MT8110 SoCs. MT8512/MT8110 SoCs puts the tune register at top layer, so need add new code to support it. Signed-off-by: mingming lee <mingming.lee@mediatek.com>

2019-10-25mmc: mtk-sd: add a dts property cd-active-high for builtin-cd modeWeijie Gao
This patch adds a dts property cd-active-high for builtin-cd mode to make it configurable instead of using hardcoded active-low. Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>

Add support for the MT8183 in the MediaTek MMC driver. Signed-off-by: Fabien Parent <fparent@baylibre.com>
2019-07-31mmc: mtk-sd: add WATCHDOG_RESET() to prevent watchdog timeoutWeijie Gao
When reading large data in once (reading 512MiB is tested on MT7623), a watchdog timeout is triggered due to watchdog not being fed. This patch adds WATCHDOG_RESET() to msdc_start_data() so the watchdog will be fed every 1024 blocks are read/written. Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>
2019-04-23mmc: mtk-sd: fix configuration option checkFabien Parent
We either need to use IS_ENABLED(CONFIG_FOO) or CONFIG_IS_ENABLED(FOO). IS_ENABLE(FOO) will always return false. This commit fixes the comparison by using the CONFIG_IS_ENABLED(FOO) syntax. Signed-off-by: Fabien Parent <fparent@baylibre.com>

2019-04-23mmc: mtk-sd: add source_cg clock supportFabien Parent
Some MediaTek SoC need an additional clock "source_cg". Enable this new clock. We reuse the same clock name as in the kernel. Signed-off-by: Fabien Parent <fparent@baylibre.com> Acked-by: Ryder Lee <ryder.lee@mediatek.com>
2019-01-26mmc: mtk-sd: fix SPL compilation when GPIO=y and SPL_GPIO=nFabien Parent
It is not possible to link the SPL image when CONFIG_GPIO is enabled but CONFIG_SPL_GPIO is not. Use the IS_ENABLED macro instead to correctly check whether CONFIG_{SPL_}GPIO is enabled. This commit fixes the following errors: * undefined reference to `dm_gpio_get_value * undefined reference to `gpio_request_by_name' Signed-off-by: Fabien Parent <fparent@baylibre.com> [trini: Move guard to fix warning in msdc_ops_get_wp()] Signed-off-by: Tom Rini <trini@konsulko.com>
2019-01-26mmc: mtk-sd: fix possible incomplete read opsFabien Parent
The code is checking for incomplete read when it see the INT_XFER_COMPL flag, but it forget to first check whether there is anything left in the FIFO to copy to the RX buffer. This means that sometimes we will get errors because of erroneous incomplete read operation. This commit fixes the driver re-ordering the code so that we first check for data inside the RX fifo and only after check the status of the INT_XFER_COMPL flag.
