[PATCH 2/3] spi: rockchip: Drop unused and broken CR0 macros
From: John Madieu
Date: Sat Apr 25 2026 - 05:31:33 EST
Two CTRLR0 macros are defined but never referenced, and both are wrong:
- CR0_XFM_MASK shifts by SPI_XFM_OFFSET, which does not exist anywhere
in the tree. The intended symbol is CR0_XFM_OFFSET.
- CR0_MTM_OFFSET is defined as 0x21, i.e. bit 33 of a 32-bit register.
The value is meaningless and the macro is unused.
Drop both. They can be re-introduced correctly when an actual user
appears.
