drivers: clk: add fu740 support

2021-05-31T08:35:54+00:00

Add fu740 support. One abstract layer is added for supporting
multiple chips such as fu540 and fu740.

treewide: Convert macro and uses of section(foo) to section("foo")

2021-05-24T18:21:30+00:00

This commit does the same thing as Linux commit 33def8498fdd.

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.

Remove the quote operator # from compiler_attributes.h __section macro.

Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

clk: renesas: Deduplicate gen3_clk_get_rate64() PLL handling

2021-05-21T13:00:17+00:00

Most of the PLLx, MAIN, FIXED clock handlers are calling very similar
code, which determines parent rate and then applies multiplication and
division. The only difference is whether multiplication is fixed factor
or coming from CRx register. Deduplicate the code into a single function.

clk: renesas: Add register pointers into struct cpg_mssr_info

2021-05-21T13:00:17+00:00

Base on Linux v5.10-rc2, commit 8b652aa8a1fb by Yoshihiro Shimoda

clk: renesas: Pass struct cpg_mssr_info to renesas_clk_endisable()

2021-05-21T13:00:17+00:00

CPG IP in some specific Renesas SoCs (i.e. new R8A779A0 V3U SoC)
requires a different setting procedure. Make struct cpg_mssr_info
accessible to handle the clock setting in that case.

clk: renesas: Make reset controller modemr register offset configurable

2021-05-21T13:00:17+00:00

The MODEMR register offset changed on R8A779A0, make the MODEMR offset
configurable. Fill the offset in on all clock drivers. No functional
change.

struct cpg_mssr_info" by Hai Pham

clk: renesas: Add support for RPCD2 clock

2021-05-21T13:00:17+00:00

This supports RPCD2 clock handling. While at it, add the check point
for RPC-IF clock RPCD2 Frequency Division Ratio, since it must be odd
number

clk: renesas: Fix Realtime Module Stop Control Register offsets

2021-05-21T13:00:17+00:00

This patch fixes Realtime Module Stop Control Register (RMSTPCR) offsets
based on R-Car Gen3, H2/M2/M2N/E2/E2X hardware user's manual.
The r8a73a4 only has RMSTPCR0 - RMSTPCR5 so this calculation change
doesn't affect it.
