[PATCH v2 0/4] LoongArch: Introduce the Loongson-2K MMC host controller driver

[Binbin Zhou <zhoubinbin@loongson.cn>]

Hi all:

This patchset introduce the MMC host controller on Loongson-2K series
CPUs.

They are similar, except for the interface characteristics and the use of
DMA engine, specifically, the Loongson-2K0500/Loongson-2K1000 use an
externally shared APBDMA engine, while the Loongson-2K2000 uses an
internally exclusive DMA.

Based on this, I'm splitting the driver into two patches.

List of the patchset:
Patch1: bindings for Loongson-2K0500/Loongson-2K1000;
Patch2: driver for MMC controller using externally shared APBDMA engine;
Patch3: bindings for Loongson-2K2000;
Patch4: driver for MMC controller using internally exclusive DMA.

Thanks.

-------
V2:

patch(1/4):
 - Add reg define for each reg entry.

patch(2/4):
 - Put all code in the c-file;
 - Use mmc_from_priv() instead of host->mmc;
 - Use sdio_signal_irq() instead of mmc_signal_sdio_irq();
 - Use devm_mmc_alloc_host() instead of mmc_alloc_host();
 - Use mmc_regulator_get_supply();

patch(4/4):
 - Add fix_cmd_interrupt function which is needed by Loongson-2K2000.
