Subject[PATCH 5.0 213/246] pinctrl: sh-pfc: r8a77995: Fix MOD_SEL bit numbering
Date
5.0-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 5219aa33caec2f7b68eda2b7e4ab8e276f323254 ]

MOD_SEL register bit numbering was different from R-Car D3 SoC and
R-Car H3/M3-[WN] SoCs.

MOD_SEL 1-bit H3/M3-[WN] D3
=============== ========== =====
Set Value = H'0 b'0 b'0
Set Value = H'1 b'1 b'1

MOD_SEL 2-bits H3/M3-[WN] D3
=============== ========== =====
Set Value = H'0 b'00 b'00
Set Value = H'1 b'01 b'10
Set Value = H'2 b'10 b'01
Set Value = H'3 b'11 b'11

MOD_SEL 3-bits H3/M3-[WN] D3
=============== ========== =====
Set Value = H'0 b'000 b'000
Set Value = H'1 b'001 b'100
Set Value = H'2 b'010 b'010
Set Value = H'3 b'011 b'110
Set Value = H'4 b'100 b'001
Set Value = H'5 b'101 b'101
Set Value = H'6 b'110 b'011
Set Value = H'7 b'111 b'111

This patch replaces the #define name and value of MOD_SEL.
