+Driver for the PWM block in Qualcomm IPQ6018 line of SoCs. Based on
+driver from downstream Codeaurora kernel tree. Removed support for older
+(V1) variants because I have no access to that hardware.
+
+Tested on IPQ5018 and IPQ6010 based hardware.

+---
+v18:
+
+ Added hardware notes and limitations based on own findings as
+ requested. NOTE: there's no publically available datasheet though.
+
+ Expanded comment on REG1_UPDATE to indicate that when this bit is set,
+ values for div and pre-div take effect. The hardware automatically
+ unsets it when the change is completed.
+
+ Added newline between MACRO definition and next comment
+
+ In config_div_and_duty, used mul_u64_u64_div_u64 to avoid overflow
+
+ Removed unncessary restriction of pwm_div to MAX_DIV - 1 after testing
+
+ Constrain pre_div to MAX_DIV is pre_div calculated is > MAX_DIV
+
+ Use of mul_u64_u64_div_u64 in .apply
+
+ Skip calculation of period and duty cycle when PWM_ENABLE REG is unset
+
+ Set duty cycle to period value when calculated duty cycle > period to
+ return a valid config
+
+ Removed .npwm as it's taken care of in devm_pwmchip_alloc
+
+ Added call to devm_clk_rate_exclusive_get to lock the clock rate
+
+ Start all kernel messages with a capital letter and end with \n.
+
+v17:
+
+ Removed unnecessary code comments
+
+v16:
+
+ Simplified code to calculate divs and duty cycle as per Uwe's comments
+
+ Removed unused pwm_chip struct from ipq_pwm_chip struct
+
+ Removed unnecessary cast as per Uwe's comment
+
+ Replaced devm_clk_get & clk_prepare_enable by devm_clk_get_enabled
+
+ Replaced pwmchip_add by devm_pwmchip_add and removed .remove function
+
+ Removed .owner from driver struct
+
+v15:
+
+ No change
+
+v14:
+
+ Picked up the R-b tag
+
+v13:
+
+ Updated the file name to match the compatible
+
+ Sorted the properties and updated the order in the required field
+
+ Dropped the syscon node from examples
+
+v12:
+
+ Picked up the R-b tag
+
+v11:
+
+ No change
+
+v10:
+
+ No change

++ * Hardware notes / Limitations:
++ * - The PWM controller has no publicly available datasheet.
++ * - Each of the four channels is programmed via two 32-bit registers
++ * (REG0 and REG1 at 8-byte stride).
++ * - Period and duty-cycle reconfiguration is fully atomic: new divider,
++ * pre-divider, and high-duration values are latched by setting the
++ * UPDATE bit (bit 30 in REG1). The hardware applies the new settings
++ * at the beginning of the next period without disabling the output,
++ * so the currently running period is always completed.
++ * - On disable (clearing the ENABLE bit 31 in REG1), the hardware
++ * finishes the current period before stopping the output. The pin
++ * is then driven to the inactive (low) level.
++ * - Upon disabling, the hardware resets the pre-divider (PRE_DIV) and divider
++ * fields (PWM_DIV) in REG0 and REG1 to 0x0000 and 0x0001 respectively.
++ * - Only normal polarity is supported.

+Describe the PWM block on IPQ9574.
+
+Although PWM is in the TCSR area, make pwm its own node as simple-mfd
+has been removed from the bindings and as such hardware components
+should have its own node.
