This patch series adds a simple driver for the Samsung S5P/Exynos SoC
series MIPI CSI-2 receiver (MIPI CSIS) and MIPI DSI transmitter (MIPI
DSIM) DPHYs, using the generic PHY framework. Previously the MIPI
CSIS and MIPI DSIM used a platform callback to control the PHY power
enable and reset bits. This non-generic platform code supporting only
limited set of SoCs is now removed.
This completes migration to the device tree of the Exynos/S5P MIPI CSI
slave device driver.
Changes since v4:
- updated to the latest version of the generic PHY framework - removed
PHY labels from the platform data structure. There is already no need
for non-dt support in this PHY driver so the platform data where any
struct phy_init_data would be passed is not added.
Changes since v3 (only patch 1/5):
- replaced spin_(un)lock_irq_{save,restore} with spin_{lock,unlock}.
- DT binding file renamed to samsung-phy.txt, so it can be used for
other PHYs as well,
- removed <linux/delay.h> inclusion,
- added missing spin_lock_init().
Changes since v2:
- adapted to the generic PHY API v9: use phy_set/get_drvdata(),
- fixed of_xlate callback to return ERR_PTR() instead of NULL,
- namespace cleanup, put "GPL v2" as MODULE_LICENSE, removed pr_debug,
- removed phy id check in __set_phy_state().
Changes since v1:
- enabled build as module and with CONFIG_OF disabled,
- added phy_id enum,
- of_address_to_resource() replaced with platform_get_resource(),
- adapted to changes in the PHY API v7, v8 - added phy labels,
- added MODULE_DEVICE_TABLE() entry,
- the driver file renamed to phy-exynos-mipi-video.c,
- changed DT compatible string to "samsung,s5pv210-mipi-video-phy",
- corrected the compatible property's description.
- patch 3/5 "video: exynos_dsi: Use generic PHY driver" replaced
with a patch modifying the MIPI DSIM driver which is currently
in mainline.
