Subject: [PATCH] dt-bindings: reset: fix double id on rk3562-cru reset ids
Date: Wed, 12 Mar 2025 22:59:23 +0100	[thread overview]
Message-ID: <20250312215923.275625-1-heiko@sntech.de> (raw)

Id 173 was accidentially used two times for SRST_P_DDR_HWLP and
SRST_P_DDR_PHY. This makes both resets ambiguous and also causes build
warnings like:

drivers/clk/rockchip/rst-rk3562.c:21:57: error: initialized field overwritten [-Werror=override-init]
   21 | #define RK3562_DDRCRU_RESET_OFFSET(id, reg, bit) [id] = (0x20000*4 + reg * 16 + bit)
      |                                                         ^

  266 |         RK3562_DDRCRU_RESET_OFFSET(SRST_P_DDR_PHY, 0, 8),
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/clk/rockchip/rst-rk3562.c:21:57: note: (near initialization for 'rk3562_register_offset[173]')
   21 | #define RK3562_DDRCRU_RESET_OFFSET(id, reg, bit) [id] = (0x20000*4 + reg * 16 + bit)
      |                                                         ^
drivers/clk/rockchip/rst-rk3562.c:266:9: note: in expansion of macro 'RK3562_DDRCRU_RESET_OFFSET'
  266 |         RK3562_DDRCRU_RESET_OFFSET(SRST_P_DDR_PHY, 0, 8),
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~

To fix that issue give SRST_P_DDR_PHY a new and now unique id.

The original patch did go with the reset of the clock controller code
into the clock tree, so this patch should of course also go that way.

I also don't have anything more open for the 6.15 merge window, so
clock-maintainers could just apply this patch on top of the main changes.
