2016-02-25drm/fsl-dcu: fix register initializationStefan Agner1-2/+2
The layer enumeration start with 0 (0-15 for LS1021a and 0-63 for Vybrid) whereas the register enumeration start from 1 (1-10 for LS1021a and 1-9 for Vybrid). The loop started off from 0 for both iterations and initialized the number of layers inclusive, which is one layer too many. All extensively written registers seem to be unassigned, it seems that the write to those registers did not do any harm in practice. Signed-off-by: Stefan Agner <[email protected]>
2016-02-25drm/fsl-dcu: use mode flags for hsync/vsync polarityStefan Agner2-3/+9
The current default configuration is as follows: - Invert VSYNC signal (active LOW) - Invert HSYNC signal (active LOW) The mode flags allow to specify the required polarity per mode. Furthermore, none of the current driver settings is actually a standard polarity. This patch applies the current driver default polarities as explicit flags to the display which has been introduced with the driver (NEC WQVGA "nec,nl4827hc19-05b"). The driver now also parses the flags field and applies the configuration accordingly, by using the following values as standard polarities: (e.g. when no flags are specified): - VSYNC signal not inverted (active HIGH) - HSYNC signal not inverted (active HIGH) Acked-by: Thierry Reding <[email protected]> Signed-off-by: Stefan Agner <[email protected]>
2016-02-25drm/fsl-dcu: fix alpha blendingStefan Agner2-12/+23
Fix alpha blending by enabling alpha blending for the whole frame if a color mode with alpha channel is selected (DRM_FORMAT_ARGB*). Also support color modes without alpha channel (DRM_FORMAT_XRGB*) by just not enabling alpha blending on layer level. Signed-off-by: Stefan Agner <[email protected]>
2016-02-25drm/fsl-dcu: mask all interrupts on initializationStefan Agner1-4/+1
The state of the interrupt mask register on initialization is unknown, e.g. U-Boot could already used the DCU. So depending on the boot loader, the outcome of the interrupt mask register could be different. A defined state is much more preferable. Also, there is no value in keeping interrupts enabled which we don't need. Therefor, mask all interrupts on initialization. Signed-off-by: Stefan Agner <[email protected]>
2016-02-25drm/fsl-dcu: handle initialization errors properlyStefan Agner1-4/+20
If initialization fails (e.g. due to missing panel node or deferred probe) make sure to roll-back all operations and return the error code. Signed-off-by: Stefan Agner <[email protected]>
2016-02-25drm/fsl-dcu: avoid memory leak on errorsStefan Agner2-1/+7
Improve error handling during CRTC initialization. Especially avoid memory leaks in the primary plane initialization error path. Signed-off-by: Stefan Agner <[email protected]>
2016-02-25drm/fsl-dcu: remove regmap return value checksStefan Agner3-188/+99
It is not common to do regmap return value checks, especially not for memory mapped device. We can rule out most error returns since the conditions are static and we know they are ok (e.g. offset aligned to register stride). Also without proper error handling they are not really valuable for the user. Hence remove most of them. The check in the interrupt handler is worth keeping since a volatile register won't be readable in case register caching is still enabled. Signed-off-by: Stefan Agner <[email protected]>
2016-02-25drm/fsl-dcu: specify volatile registersStefan Agner1-1/+11
Since we are using cached registers, we need to specify volatile registers explicitly to avoid reading their value from the cache. This allows to read the correct interrupt status in fsl_dcu_drm_irq and clear the asserted bits only. Signed-off-by: Stefan Agner <[email protected]>
