[PATCH v18 00/12] Add Renesas RZ/G3L SD/eMMC support

[Biju]

From: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>

RZ/G3L SoC has:

Channel 0 supports SD and eMMC (including HS400/HS400ES).
Channel 1 supports SD and eMMC (except for HS400).
Channel 2 supports SD.

The SoC supports a maximum frequency of 150 MHz. The SD0 interface does
not support IOVS and PWEN in the SDHI register (no internal regulator),
unlike SD1 and SD2. It has an internal divider for all modes except HS400.
It also has a 2048-bit divider compared to 512 on others. Moreover
RZ/G3L supports HS400 enhanced strobe mode.

v17->v18:
 * Collected tag
 * Merged patch #4 and #5 and updated commit description
 * Annotated the empty sentinel entries in the OF match tables with a
   "Sentinel." comment for clarity.
 * Retained the tag as it is a trivial cleanup.
 * New patches drop struct renesas_sdhi_hw_info, instead using
   renesas_sdhi_of_data and tmio_mmc_data.
 * Dropped clk, pinctrl, SoC, and board dtsi from this patch series;
   will send later.
v1->v17:
 * Collected tag for binding patch.
 * Resending the series as there is an issue with patch threading from
   patch #14.
