* ramips: move MTK MMC driver to files directoryDENG Qingfang2020-04-047-4021/+0
| | | | | | | Move MTK MMC driver from "files-4.14" to "files" so kernel 5.4 can use it Signed-off-by: DENG Qingfang <dengqf6@mail2.sysu.edu.cn>
* ramips: mtk-mmc: mt76x8: check ESD_MODE before applying AGPIO_CFGChuanhong Guo2019-07-161-8/+4
| | | | | | | | | | | | | | | | | | | | | | | Since mt76x8an ver1 eco2, SDXC pins can be switched to the following pinmap: sd_d1 -> PAD_I2S_SDI sd_d0 -> PAD_I2S_WS sd_cmd -> PAD_I2S_CLK sd_d3 -> PAD_I2C_SCLK sd_d2 -> PAD_I2C_SD sd_clk -> PAD_GPIO0 sd_wp -> PAD_TXD1 sd_cd -> PAD_RXD1 To use this pinmap, one would need to set ESD_MODE bit (bit 15) to 1 in GPIO1_MODE and switch other used pads into GPIO mode. In this mode, we don't need to switch ethernet pins to digital pad. Check ESD_MODE bit before applying AGPIO_CFG and use rt_sysc_m32 to set it. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
* ramips: drop obsolete sd card driver codeMathias Kresin2018-09-062-20/+4
| | | | | | | | | | | | | | | | | The pinmux for all SoCs using this driver is now set via the pinmux. It makes this code obsolete. Some of the code targeting the mt76x8 SoCs is still required. The sd card pins share the pads with the EPHY. These pads need to be switched to digital mode if the pins are used for sd cards. The eMMC 8-bit mode has to be enabled via pinmux instead of a kernel option. The uart2 group need to be set to function "sdxc d5 d4", pwm1 to "sdxc d6" and pwm0 to "sdxc d7" to do so. It can't be done by as part of a default pinmux, as it would break the normal operation of uart2. Signed-off-by: Mathias Kresin <dev@kresin.me>
* Revert "ramips: mmc: Fix init for MT7628AN"Jo-Philipp Wich2018-08-302-16/+1
| | | | | | | | | | This reverts commit 3a8efaef00d6b7317c46fe6b7e923912d8bf3500. The change reportedly breaks UART2 on some boards. Furthermore it uses bitwise logic on an uninitialized variable and fails to explain what it is fixing exactly. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
* ramips: mmc: Fix init for MT7628ANLoveSy2018-07-302-1/+16
| | | | | | | | There is another thing about crc to do when initialize SD card on MT7628. This commit is to fix this init issue. Signed-off-by: LoveSy <shana@zju.edu.cn>
* ramips: mmc: Add back some non-mt7621 code that staging removedRosen Penev2018-06-081-1/+17
| | | | | | | | | | This reverts commit 8a570921b5ba49a2d3824f1220e4c53809063468. This seems to have been accidentally reverted. This fixes mt7620 and mt7628. Signed-off-by: Rosen Penev <rosenp@gmail.com> Acked-by: Daniel Golle <daniel@makrotopia.org>

* ramips: mmc: Sync with staging driverRosen Penev2018-05-185-3417/+2693
| | | | | | | | | | | | | | Mostly whitespace cleanups. Some unneeded code was removed. MMC init was also moved to the probe function as in 6069bdd The cleanup commits are over 100, making it hard to do them individually. Tested on GnuBee PC1 with an SD card being used as swap.

* ramips: move mtk-mmc init to probe function to avoid breaking NAND flashFelix Fietkau2018-05-081-36/+28
| | | | | | | The driver messes with the pin control settings - MMC and NAND are mutually exclusive Signed-off-by: Felix Fietkau <nbd@nbd.name>
* ramips: mtk-mmc: don't advertise highmem support.NeilBrown2018-04-051-0/+1
| | | | | | | | | | | | | | | | of_dma_configure() sets a default ->dma_mask of DMA_BIT_MASK(32), claiming devices can DMA from the full 32bit address space. The mtk-mmc driver does not support access to highmem pages, so it is really limited to the bottom 512M (actually 448M due to 64M of IO space). Setting ->dma_mask to NULL causes mmc_setup_queue() to fall-back to using BLK_BOUNCE_HIGH to tell the block layer to use a bounce-buffer for any highmem pages requiring IO.
