* | backlight: pwm_bl: Fix GPIO out for unimplemented .get_direction()Geert Uytterhoeven2017-04-191-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 7613c922315e308a ("backlight: pwm_bl: Move the checks for initial power state to a separate function") not just moved some code, but made slight changes in semantics. If a gpiochip doesn't implement the optional .get_direction() callback, gpiod_get_direction always returns -EINVAL, which is never equal to GPIOF_DIR_IN, leading to the GPIO not being configured for output. To avoid this, invert the test and check for not GPIOF_DIR_OUT instead, like the original code did. This restores the display on r8a7740/armadillo.

On arm64 PCI systems, the entire PCI hierarchy is reconfigured from scratch at boot. This may result in the GOP framebuffer address to become stale, if the BAR covering the framebuffer is modified. This will cause the framebuffer to become unresponsive, and may in some cases result in unpredictable behavior if the range is reassigned to another device. So add a non-x86 quirk to the EFI fb driver to find the BAR associated with the GOP base address, and claim the BAR resource so that the PCI core will not move it.

* | fbdev/ssd1307fb: fix optional VBAT supportBastian Stender2017-04-071-8/+16
|/ | | | | | | | | | | | | | | | | | | | | | | | | SSD1306 needs VBAT when it is wired in charge pump configuration only. Other controllers of the SSD1307 family do not need it at all. This was introduced by commit ba14301e0356 ("fbdev/ssd1307fb: add support to enable VBAT"). Without VBAT configuration the driver now fails with: failed to get VBAT regulator: -19 This is caused by misinterpretation of devm_regulator_get_optional which "returns a struct regulator corresponding to the regulator producer or IS_ERR() condition". Handle -ENODEV without bailing out and making VBAT support really optional.

| | | | | | | | | | | | | | | | | | Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently when a simplefb needs both clocks and regulators and one of the regulators returns -EPROBE_DEFER when we try to get it, we end up disabling the clocks. This causes the screen to go blank; and in some cases my cause hardware state to be lost resulting in the framebuffer not working at all. This commit splits the get and enable steps and only enables clocks and regulators after successfully getting all of them, fixing the disabling of the clocks which were left enabled by the firmware setting up the simplefb.

| * fbcon: Fix vc attr at deinitTakashi Iwai2017-01-111-27/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fbcon can deal with vc_hi_font_mask (the upper 256 chars) and adjust the vc attrs dynamically when vc_hi_font_mask is changed at fbcon_init(). When the vc_hi_font_mask is set, it remaps the attrs in the existing console buffer with one bit shift up (for 9 bits), while it remaps with one bit shift down (for 8 bits) when the value is cleared. It works fine as long as the font gets updated after fbcon was initialized. However, we hit a bizarre problem when the console is switched to another fb driver (typically from vesafb or efifb to drmfb). At switching to the new fb driver, we temporarily rebind the console to the dummy console, then rebind to the new driver. During the switching, we leave the modified attrs as is. Thus, the new fbcon takes over the old buffer as if it were to contain 8 bits chars (although the attrs are still shifted for 9 bits), and effectively this results in the yellow color texts instead of the original white color, as found in the bugzilla entry below. An easy fix for this is to re-adjust the attrs before leaving the fbcon at con_deinit callback. Since the code to adjust the attrs is already present in the current fbcon code, in this patch, we simply factor out the relevant code, and call it from fbcon_deinit().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code calculates the number of color map entries as 1 << info->var.bits_per_pixel. For 32bpp modes, 1 << 32 is 0 when written to an int variable. As a consequence, the subsequent copying of the default (non-empty) color map into our newly allocated color map fails and imxfb's probe function returns an error. On both imx1 and imx21 platforms, the color map is used only for modes with <= 8bpp. By allocating 256 entries for the color map, we're on the safe side.
