[RFC 4/7] mfd: ocelot-spi: Change the regmap stride to reflect the real one
From: Maxime Chevallier
Date: Fri Mar 24 2023 - 05:37:42 EST
When used over SPI, the register addresses needs to be translated,
compared to when used over MMIO. The translation consists in applying an
offset with reg_base, then downshifting the registers by 2. This
actually changes the register stride from 4 to 1.
