2016-11-28drm/fsl-dcu: introduce kernel parameter to specify fbdev depthStefan Agner
Add a kernel parameter legancyfb_depth (like the i.MX drm driver) to control the legancy fbdev depth. Default to the so far hard coded depth of 24-bit. Currently changing the framebuffer depth is not possible from user space when using the fbdev emulation layer... This provides a rudimentary mechanism to change depth without having to change kernel code. Signed-off-by: Stefan Agner <stefan@agner.ch>
2016-11-28drm/fsl-dcu: remove separate compilation unit for fbdev emulationStefan Agner
The separate file fsl_dcu_drm_fbdev.c only initialized fbdev emulation which is a one-line operation. There is not much more code on sight which justifies a separate file, hence call the initialization helper directly from the drv file. Signed-off-by: Stefan Agner <stefan@agner.ch>

2016-11-28drm/fsl-dcu: disable outputs before unloading driverStefan Agner
Make sure that all outputs are disabled before unloading the DRM driver. Otherwise vblank handling is not shut down properly and warnings such as this appear: WARNING: CPU: 0 PID: 540 at drivers/gpu/drm/drm_irq.c:339 drm_vblank_cleanup+0x5c/0x94 Signed-off-by: Stefan Agner <stefan@agner.ch>
2016-11-28drm/fsl-dcu: unload driver before disabling clocksStefan Agner
Use drm_put_dev to unload the driver before disabling clocks. Otherwise the driver might read a register during unload which leads to an external abort. Signed-off-by: Stefan Agner <stefan@agner.ch>
2016-11-08drm/fsl-dcu: disable planes before disabling CRTCStefan Agner
After disabling and reenabling the CRTC the DCU sometimes got stuck displaying the whole screen with a solid color. Disabling and reenabling the CRTC did not recover from the situation. This was often reproducable by just restarting the X-Server. The disabling sequence is not explicitly documented. But it turns out that disabling the planes before disabling the CRTC seems to prevent the above situation from happening. Use the callback ->atomic_disable instead of ->disable which allows to use the drm_atomic_helper_disable_planes_on_crtc() helper to disable planes before disabling the controller.

Use the UPDATE_MODE READREG bit to initiate a register transfer on flush. This makes sure that we flush all registers only once for all planes. Signed-off-by: Stefan Agner <stefan@agner.ch>
2016-11-08drm/fsl-dcu: do not update when modifying irq registersStefan Agner
The IRQ status and mask registers are not "double buffered" according to the reference manual. Hence, there is no extra transfer/update write needed when modifying these registers. Signed-off-by: Stefan Agner <stefan@agner.ch>

2016-10-19drm/fsl-dcu: do not transfer registers on plane initStefan Agner

2016-10-19drm/fsl-dcu: enable TCON bypass mode by defaultStefan Agner

2016-06-08drm/fsl-dcu: use flat regmap cacheStefan Agner
Using flat regmap cache instead of RB-tree to avoid the following lockdep warning on driver load: WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:2755 lockdep_trace_alloc+0x15c/0x160() DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags)) The RB-tree regmap cache needs to allocate new space on first writes. However, allocations in an atomic context (e.g. when a spinlock is held) are not allowed. The function regmap_write calls map->lock, which acquires a spinlock in the fast_io case. Since the FSL DCU driver uses MMIO, the regmap bus of type regmap_mmio is being used which has fast_io set to true. Use flat regmap cache and specify max register to be large enouth to cover all registers available in LS1021a and Vybrids register space.

This was added in commit 0a3e67a4caac273a3bfc4ced3da364830b1ab241 Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Tue Sep 30 12:14:26 2008 -0700 drm: Rework vblank-wait handling to allow interrupt reduction. to stay backwards-compatible with old UMS code that didn't even tell the kernel when it did a modeset, so that the kernel could save/restore vblank counters. At worst this means vblanks will be somewhat funky on a setup that very likely no one still runs. So let's just nuke it. Plan B would be to set it unconditionally in drm_vblank_init for kms drivers, instead of in each driver separately. So if this patch breaks anything please only restore the hunks in drmP.h and drm_irq.c, plus add a check for DRIVER_MODESET in drm_vblank_init. Stumbled over this in a discussion on irc with Chris.

2016-05-05drm/fsl-dcu: use bus_flags for pixel clock polarityStefan Agner
The drivers current default configuration drives the pixel data on rising edge of the pixel clock. However, most display sample data on rising edge... This leads to color shift artefacts visible especially at edges. This patch changes the relevant defines to be useful and actually set the bits, and changes pixel clock polarity to drive the pixel data on falling edge by default. The patch also adds an explicit pixel clock polarity flag to the display introduced with the driver (NEC WQVGA "nec,nl4827hc19-05b") using the new bus_flags field to retain the initial behavior.
