Now that we have platform-specific infrastructure for the dw i3c driver, add platform support for the ASPEED AST2600 SoC. The AST2600 has a small set of "i3c global" registers, providing platform-level i3c configuration outside of the i3c core. For the ast2600, we need a couple of extra setup operations: - on probe: find the i3c global register set and parse the SDA pullup resistor values - on init: set the pullups accordingly, and set the i3c instance IDs Signed-off-by: Jeremy Kerr <jk@codeconstruct.com.au> Reviewed-by: Joel Stanley <joel@jms.id.au> Link: https://lore.kernel.org/r/20230331091501.3800299-4-jk@codeconstruct.com.au Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com> |
