The first patch of this series introduces multi-page support using the
regmap infrastructure. This simplifies the code and improves regmap caching.
The second patch introduces a spd5118-specific regmap bus to implement
SMBus accesses. This solves a problem seen with i801 I2C controllers
when writing to the chip. The I2C_FUNC_SMBUS_I2C_BLOCK support implemented
in those controllers does not work with spd5118 compatible chips, so
byte-by-byte access needs to be used explicitly.
The third patch adds support for spd5118 compatible chips which follow
the standard literally and block access to volatile registers if not
on page 0.
RFT: I was able to test the code on AMD systems using the piix4 I2C
controller. It needs testing with i801 controllers and with Renesas
chips.
v2: Added patches 1 and 2; simplified patch 3 to rely on regmap
based paging.
Hi,
i also have an AMD system and DRAM chips without the Renesas controller, but still:
