2019-11-13mmc: sdhci-of-arasan: Add Support for Intel LGM SDXCRamuthevar Vadivel Murugan1-0/+15
The current arasan sdhci PHY configuration isn't compatible with the PHY on Intel's LGM(Lightning Mountain) SoC devices. Therefore, add a new compatible, to adapt the Intel's LGM SDXC PHY with arasan-sdhc controller to configure the PHY.

2019-11-13mmc: mmci: sdmmc: add busy_complete callbackLudovic Barre3-0/+47
This patch adds a specific busy_complete callback for sdmmc variant. sdmmc has 2 status flags: -busyd0: This is a hardware status flag (inverted value of d0 line). it does not generate an interrupt. -busyd0end: This indicates only end of busy following a CMD response. On busy to Not busy changes, an interrupt is generated (if unmask) and BUSYD0END status flag is set. Status flag is cleared by writing corresponding interrupt clear bit in MMCICLEAR. The legacy busy completion has no dedicated interrupt for the end of busy, so it's must monitor step by step the busy progression. On sdmmc variant, this procedure is not needed, it's just need to wait the busyd0end interrupt. Signed-off-by: Ludovic Barre <ludovic.barre@st.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2019-11-13mmc: mmci: add busy_complete callbackLudovic Barre2-62/+73
This patch adds busy_completion callback at mmci_host_ops to allow to define a specific busy completion by variant. The legacy code corresponding to busy completion used by ux500 variants is moved to ux500_busy_complete function.

2019-11-13mmc: mmci: add hardware busy timeout featureLudovic Barre2-5/+40
In the stm32_sdmmc variant, the datatimer is active not only during data transfers with the DPSM, but also while waiting for the busyend IRQs from commands having the MMC_RSP_BUSY flag set. This leads to an incorrect IRQ being raised to signal MCI_DATATIMEOUT error, which simply breaks the behaviour. Address this by updating the datatimer value before sending a command having the MMC_RSP_BUSY flag set. To inform the mmc core about the maximum supported busy timeout, which also depends on the current clock rate, set ->max_busy_timeout (in ms).
