Commit Message

Ralph Siemsen May 13, 2023, 1:36 a.m. UTC 
Clock driver for the Renesas RZ/N1 SoC family. This is based on
Linux kernel 6.2.y drivers/clk/renesas/r9a06g032-clocks.c as found in
commit 02693e11611e ("clk: renesas: r9a06g032: Repair grave increment error"),
with the following additional patch series applied:
https://lore.kernel.org/linux-renesas-soc/20230301215520.828455-1-ralph.siemsen@linaro.org/

Notable difference: this version avoids allocating a 'struct clk'
for each clock source, as this is problematic before relocation.
Instead, it uses the same approach as existing Renesas R-Car Gen2/3
clock drivers, using a temporary structure filled on-the-fly.

(no changes since v6)

Changes in v6:
- add macros for RSTEN register and its bits

Changes in v5:
- eliminate "err" in probe function

Changes in v4:
- commit message now includes hash of Linux upon which this is based
  as well as the additional patches (clock table cleanups)
- sync changes from review on linux patches, including
  - move RB macro higher up and document it, matching Linux driver
  - use multiply/divide instead of shifts for computing reg address
  - improve comments for clock gate, descriptor structures

Changes in v3:
- convert data table to explicit reg/bit numbers
- drop the unused scon, mirack, mirstat fields
- added some kernel docs to structures
- use enum for type field of struct r9a06g032_clkdesc
- cleanup macros for one assignment per line
- add a macro for top-most clock ID value ~0
- use dev_dbg() instead of debug/print
- minor reformatting, declarations before code, etc
- !foo instead of foo == 0
- IS_ERR / PTR_ERR where appropriate
- implement div_table handling
- remove some #if 0 old test code

+ * @bit: which bit (0 to 31) in the register
+ *
+ * This structure is used to compactly encode the location

+ * This allows encoding an offset up to 0x1FFC (8188) bytes.
+ *
+ * Helper macro RB() takes care of converting the register
+ * offset from bytes to 32-bit words.
