Current API for PHY package are limited to single address to configure global settings for the PHY package. It was found that some PHY package (for example the qca807x, a PHY package that is shipped with a bundle of 5 PHY) requires multiple PHY address to configure global settings. An example scenario is a PHY that have a dedicated PHY for PSGMII/serdes calibrarion and have a specific PHY in the package where the global PHY mode is set and affects every other PHY in the package. Change the API in the following way: - Change phy_package_join() to take the base addr of the PHY package instead of the global PHY addr. - Make __/phy_package_write/read() require an additional arg that select what global PHY address to use by passing the offset from the base addr passed on phy_package_join(). Each user of this API is updated to follow this new implementation following a pattern where an enum is defined to declare the offset of the addr. We also drop the check if shared is defined as any user of the phy_package_read/write is expected to use phy_package_join first. Misuse of this will correctly trigger a kernel panic for NULL pointer exception. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
