| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since there are more IOT2040 variants with identical hardware but different asset tags, the asset tag matching should be adjusted to support them. For the board name "SIMATIC IOT2000", currently there are 2 types of hardware, IOT2020 and IOT2040. Both are identical regarding the intel_quark_i2c_gpio. In the future there will be no other devices with the "SIMATIC IOT2000" DMI board name but different hardware. So remove the asset tag matching from this driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AXP223 can be used both using the RSB proprietary bus, or a more traditional I2C bus. The RSB is a faster bus and provides more features (like some integrity checks on the messages), so it's usually preferrable to use it, but since it's proprietary, when we want to use the PMIC in a multi-master setup, the i2c might make sense as well.

There 2d offset above is register ACCCTL that gets written on twl6040 powerup. With error checking added to the related regcache_sync() call, the -EREMOTEIO error is reproducable on twl6040 powerup at least duovero. To fix the error, we need to wait until twl6040 is accessible after the powerup. Based on tests on omap4 duovero, we need to wait over 8ms after powerup before register write will complete without failures. Let's also make sure we warn about possible errors too. Note that we have twl6040_patch[] reg_sequence with the ACCCTL register configuration and regcache_sync() will write the new value to ACCCTL.

Since a SMC call to EL3 is required, this new driver uses regmaps similar to syscon to handle the SMC call. Since regmaps abstract out the underlying register access, the changes to drivers accessing the System Manager are minimal.

A problem showed up when a patch "moduleparam: Save information about built-in modules in separate file" was applied. With this new feature, MODULE_*() will be populated even if the callers are built-in. To avoid the build errors, the lines referencing to the undefined macro must be removed. The complete fix is to remove all MODULE_* and #include <linux/module.h> like many "make ... explicitly non-modular" commits did. For now, I am touching only the offending lines.
