2019-01-21pinctrl: sh-pfc: r8a7794: Initialize TDSEL register for ES1.0Wolfram Sang1-0/+16
Documentation for ES1.0 says that some bits in TDSEL must be set (ch 5.3.35 in R-Car E2 v0.5). However, the reset value of the register is 0, so software has to do it. Add this to the kernel driver to ensure this is really done independent of firmware versions and use whitelisting for ES versions known to need this. This is needed for some SD cards supporting SDR104 transfer mode.

The Peripheral Function Select Register 9 contains 12 fields, but the variable field descriptor contains a 13th bogus field of 3 bits.

2018-11-06pinctrl: sh-pfc: Reduce kernel size for narrow VIN channelsGeert Uytterhoeven1-2/+2
Some VIN channels support less than 24 lanes. As union vin_data always consumes space for 24 lanes, this wastes memory. Hence introduce new smaller unions vin_data12 and vin_data16, to accommodate VIN channels with only 12 or 16 lanes. This reduces the static pin controller driver size by 320 bytes for R-Car V2H, and by 96 bytes for R-Car E2.

The R8A7794 PFC driver was apparently based on the preliminary revisions of the user's manual which had some signals and MOD_SEL register fields described which the recent manual changed to reserved. Of course, these signals haven't ever been really used, which makes removing them painless. While at it, make the large *enum* look better by starting a new line each time a new row in the IPSR and MOD_SEL register field tables is started.
