But hey, --patience probably is good enough for this version, so thank you for using it!
This series aims to convert ep93xx from platform to full device tree support. The main goal is to receive ACK's to take it via Arnd's arm-soc branch. Bit thanks to Krzysztof Kozlowski for his zero-day review. Krzysztof, Sergey, i've changed some files that you have already provided tag: - dt-bindings: spi: Add Cirrus EP93xx - ata: pata_ep93xx: add device tree support Added DMA and renamed clock header file. Sergey, Damien, i've changed some files that you have already provided tag: - ata: pata_ep93xx: add device tree support Added OF DMA setup and dropped platform file. Mark, i've changed some files that you have already provided tag: - spi: ep93xx: add DT support for Cirrus EP93xx Added OF DMA setup and dropped platform file. Major updates: - reboot, pinctrl, clk are now auxiliary and instantiated from SoC driver as Stephen Boyd suggested - i moved all clock code to clk-ep93xx.c, as it no longer has a separate dt node, so XTALI is externalk for this driver and passed as index 0, and pll1, pll2 are internal and passed via pointer for parent_data - reboot bindings dropped - pinctrl and clk bindings moved to syscon YAML - xlate added for DMA, so now all DMA users use it via device tree, otherwise probe order messed up and we might end up probing before DMA with no possibility to defer probing - DMA port bindings dropped, they are described in YAML file - DMA platform code dropped - i2s, spi, pata now use OF DMA - YAML and dtsi/dts changed to reflect auxiliary conversion and DMA changes Patches should be now formated with '--patience' --- Changes in v5: - gpio: ep93xx: split device in multiple - ordered headers - use irqd_to_hwirq() - s/platform_get_irq()/platform_get_irq_optional()/ - [PATCH v4 02/42] ARM: ep93xx: add swlocked prototypes - replaced with ARM: ep93xx: add regmap aux_dev -

convert to auxiliary and use parent device tree node - moved all clocks except XTALI here - used devm version everywhere and *_parent_hw() instead of passing name where it's possible - unfortunately devm_clk_hw_register_fixed_rate doesn't have a parent index version - [PATCH v4 05/42] dt-bindings: pinctrl: Add Cirrus EP93xx - "unevaluatedProperties: false" for pins - returned "additionalProperties: false" where it was - and dropped it - pinctrl: add a Cirrus ep93xx SoC pin controller - sorted includes - convert to auxiliary and use parent device tree node - power: reset: Add a driver for the ep93xx reset - convert to auxiliary device - dt-bindings: soc: Add Cirrus EP93xx - dropped all ref to reboot, clk, pinctrl subnodes -

dt-bindings: dma: Add Cirrus EP93xx - dropped bindings header (moved ports description to YAML) - changed '#dma-cells' to 2, we use port, direction in cells so we can drop platform code completely - dma: cirrus: add DT support for Cirrus EP93xx - dropped platform probing completely - dropped struct ep93xx_dma_data replaced with internal struct ep93xx_dma_chan_cfg with port/direction - added xlate functions for m2m/m2p - we require filters to set dma_cfg before hw_setup - dt-bindings: ata: Add Cirrus EP93xx - Document DMA support - ata: pata_ep93xx: add device tree support - drop DMA platform header with data - use DMA OF so we can defer probing until DMA is up - ARM: dts: add Cirrus EP93XX SoC .dtsi -
