This was originally part of the RFC: firmware: arm_scmi: Qualcomm Vendor Protocol [1]. I've split it up so that this part can land earlier. Warnings Introduced by the series are fixed by [2] V6: * Drop patches that are already picked up. * Rebase to the latest next-20241029. V5: * Fix build error reported by kernel test robot by adding 64BIT requirement to COMPILE_TEST * Pick Rbs V4: * Move val, flag and chan to local loop variables. [Jassi] * Add cpucp mailbox to the MAINTAINERS file. [Jassi] * Move to core_initcall. [Konrad] * Skip explicitly setting txdone_irq/txdone_poll to zero. [Konrad] V3: * Fix Maintainer info in cpucp mbox bindings. [Bjorn] * Fix copyright info in cpucp driver. [Bjorn] * Drop unused APSS_CPUCP_TX_MBOX_IDR, value init and drv_data. [Bjorn/Dmitry] * Convert to lower case hex. [Bjorn] * Convert irq and dev to local variables. [Bjorn] * Replace for and if with for_each_set_bit. [Bjorn] * Document the need for spinlock. [Bjorn] * Add space after " for aesthetics. [Bjorn] * Fix err in calc and add fixes tag. [Bjorn] * Include io.h and re-order platform_device.h * Use GENMASK_ULL to generate APSS_CPUCP_RX_MBOX_CMD_MASK. V2: * Fix series version number [Rob] * Pickup Rbs from Dimitry and Rob. * Use power-domain instead of clocks. [Sudeep/Ulf] * Rename sram sub-nodes according to schema. [Dmitry] * Use BIT() instead of manual shift. [Dmitry] * Define RX_MBOX_CMD to account for chan calculation. [Dmitry] * Clear the bit instead of the entire status within the spinlock. [Dmitry] * Use dev_err_probe instead. [Dmitry] * Drop superfluous error message while handling errors from get_irq. [Dmitry] * Use devm_mbox_controller_register and drop remove path. [Dmitry] * Define TX_MBOX_CMD to account for chan calculation. * Use cpucp->dev in probe path for conformity. RFC V1: * Use x1e80100 as the fallback for future SoCs using the cpucp-mbox controller. [Krzysztoff/Konrad/Rob] * Use chan->lock and chan->cl to detect if the channel is no longer Available. [Dmitry] * Use BIT() instead of using manual shifts. [Dmitry] * Don't use integer as a pointer value. [Dmitry] * Allow it to default to of_mbox_index_xlate. [Dmitry] * Use devm_of_iomap. [Dmitry] * Use module_platform_driver instead of module init/exit. [Dmitry] * Get channel number using mailbox core (like other drivers) and further simplify the driver by dropping setup_mbox func.
