[U-Boot] [PATCH 1/4] mmc: atmel: Silence debug output
by Marek Vasut 01 Nov '15

01 Nov '15

This driver generates clearly debugging prints when changing clock speed, so silence those. Furthermore, the driver generates further prints in case a command fails to complete. The later case woud be useful, but for eMMC, command 8 can fail and it's not an error but a part of the specification. Thus, make this debug() as well.

[U-Boot] [PATCH v2 0/8] x86: Support off-chip graphics card on Intel Crown Bay
by Bin Meng 30 Oct '15

30 Oct '15

Previously when I started to look at the graphics support on Intel Crown Bay, I tried to debug IGD and off-chip graphics card but none of their vgabios can run under U-Boot. Later with a bug fixed in the 16-bit real mode and 32-bit protected mode switch, IGD vgabios can run successfully but these two PCIe graphics cards I have at hand still don't work. With recent bug fixes as an attempt to support SeaBIOS, I started to look at them again, and this time finally got both of them work. It turns out we need completely disable IGD on TunnelCreek chipset, and also get i8254 timer counter 1 set up corretly. This series also fixes several nits in the i8259/i8254 codes. In case someone is interested, the two PCIe graphics card I used for testing are: 1: XGI Technology Inc., vendor ID 0x18ca, device ID 0x0027 2: Matrox Electronics Systems Ltd., vendor ID 0x102b, device ID 0x2527 Changes in v2: - Add help for the Kconfig options Bin Meng (8): x86: Rename CONFIG_SYS_NUM_IRQS to SYS_NUM_IRQS x86: Remove dead codes wrapped by PARANOID_IRQ_TRIGGERS x86: Fix cosmetic issues in the i8254 and i8259 codes x86: Initialize i8254 timer counter 1 x86: Rename pcat_ to i8254 and i8259 accordingly x86: Move CONFIG_8259_PIC and CONFIG_8254_TIMER to Kconfig x86: queensbay: Really disable IGD x86: Move timer_init() call a bit earlier arch/x86/Kconfig | 15 +++++++++ arch/x86/cpu/interrupts.c | 2 +- arch/x86/cpu/queensbay/tnc.c | 26 ++++++++++++---- arch/x86/include/asm/arch-queensbay/tnc.h | 7 ++--- arch/x86/include/asm/i8254.h | 43 ++++++++++++-------------- arch/x86/include/asm/i8259.h | 31 ++++++++++--------- arch/x86/include/asm/interrupt.h | 2 ++ arch/x86/include/asm/u-boot-x86.h | 2 +- arch/x86/lib/Makefile | 4 +-- arch/x86/lib/i8254.c | 37 +++++++++++++++++++++++ arch/x86/lib/{pcat_interrupts.c => i8259.c} | 47 ++++++++--------------------- arch/x86/lib/interrupts.c | 10 +++--- arch/x86/lib/pcat_timer.c | 27 ----------------- arch/x86/lib/tsc_timer.c | 6 ++-- common/board_f.c | 2 +- common/board_r.c | 3 +- include/configs/x86-common.h | 3 -- 17 files changed, 141 insertions(+), 126 deletions(-) create mode 100644 arch/x86/lib/i8254.c rename arch/x86/lib/{pcat_interrupts.c => i8259.c} (70%) delete mode 100644 arch/x86/lib/pcat_timer.c -- 1.8.2.1

At present the debug UART is not selected which causes a build error. Correct this.

[U-Boot] [PATCH 00/28] dm: input: Move keyboard drivers to driver model
by Simon Glass 30 Oct '15

30 Oct '15

This series adds a new uclass for keyboards and converts some drivers over to use it. This series includes some work to remove code duplication in the keyboard drivers by updating them to use the input library (input.c). This unifies the keycode decoding logic in one place. In order to do this some enhancements are needed to the input library and these are also included. The cros_ec and tegra_kbc drivers are converted to use driver model. The i8042 driver is converted also, after various tidy-ups. The driver has some strange interactions with the cfb_console driver. This is removed in this series which is possible because the only user is x86. Some i8042 features have been dropped (the only deliberate one is the flashing cursor which does not seem to be used by any board). Also the i8042 driver currently has its own keycode decoding logic. This series removes it in favour of the input library. Therefore testing of this new driver would be appreciated. So far I have only been able to test on link, which does not have a full keyboard. Also, while German keyboard support is implemented, I am unable to test that either. These changes can be considered the first step towards moving stdio to driver model. For that to be useful we need to convert LCD and video also. Note: This series is missing the code to call the update_leds() method when the LEDs change. This needs to be added to keyboard_tstc() and keyboard_getc(). If someone is able to test this I can send a patch for that also. Simon Glass (28): dm: input: Create a keyboard uclass input: Add a device pointer to the input config input: Return -ENOSPC when there is not space input: Add the keycode translation tables separately cros_ec: Use udevice instead of cros_ec_dev for keyboard functions dm: stdio: Plumb in the new keyboard uclass dm: tegra: Convert keyboard driver to driver model dm: cros_ec: Convert cros_ec keyboard driver to driver model video: Drop unused console functions i8042: Use functions to handle register access i8042: Handle a duplicate power-on-reset response i8042: Adjust kbd_reset() to collect all failures i8042: Adjust keyboard init to assume success input: Correct keycode for Ctrl-Y input: Add a few more keyboard keycodes input: Add a function to add a keycode to the existing set input: Allow repeat filtering to be disabled input: Support the German keymap input: Adjust structure of code in process_modifier() input: Handle caps lock input: Allow updating of keyboard LEDs input: i8042: Convert to use the input library input: Add a Kconfig option for the i8042 keyboard x86: Add an i8042 device for boards that have it Drop CONFIG_ISA_KEYBOARD input: Convert i8042 to driver model video: input: Clean up after i8042 conversion input: Convert 'keyboard' driver to use input library README | 42 +-- arch/arm/Kconfig | 1 + arch/arm/mach-tegra/Kconfig | 1 + arch/sandbox/Kconfig | 3 + arch/x86/Kconfig | 6 + arch/x86/dts/bayleybay.dts | 1 + arch/x86/dts/chromebook_link.dts | 1 + arch/x86/dts/keyboard.dtsi | 5 + board/kosagi/novena/novena.c | 1 + board/mpl/pip405/README | 4 - common/stdio.c | 31 +- common/usb_kbd.c | 6 - drivers/input/Kconfig | 19 ++ drivers/input/Makefile | 4 +- drivers/input/cros_ec_keyb.c | 147 ++++----- drivers/input/i8042.c | 632 ++++++++++----------------------------- drivers/input/input.c | 202 ++++++++++--- drivers/input/keyboard-uclass.c | 84 ++++++ drivers/input/keyboard.c | 290 +++--------------- drivers/input/tegra-kbc.c | 242 +++++++-------- drivers/misc/cros_ec.c | 14 +- drivers/video/cfb_console.c | 82 +---- include/configs/MIP405.h | 5 - include/configs/MPC8536DS.h | 1 - include/configs/MPC8544DS.h | 1 - include/configs/MPC8572DS.h | 1 - include/configs/MPC8641HPCN.h | 1 - include/configs/PIP405.h | 5 - include/configs/x86-chromebook.h | 2 +- include/configs/x86-common.h | 2 +- include/cros_ec.h | 4 +- include/fdtdec.h | 1 - include/i8042.h | 6 - include/input.h | 65 +++- include/keyboard.h | 83 +++++ lib/fdtdec.c | 1 - 36 files changed, 866 insertions(+), 1130 deletions(-) create mode 100644 arch/x86/dts/keyboard.dtsi create mode 100644 drivers/input/keyboard-uclass.c -- 2.6.0.rc0.131.gf624c3d
