[U-Boot] [PATCH 0/2] tegra124: Add support for Avionic Design platform
by Julian Scheel 02 Mar '16

02 Mar '16

This adds support for the Avionic Design Tegra124 platform. It consists of the Meerkat SOM and a minimal baseboard Kein Baseboard. The as3722 is placed on a different bus as compared to nvidia Jetson, which makes the as3722 required.

[U-Boot] [PATCH] colibri-vf: Disable pull-up configuration in GPIO pin mux
by Bhuvanchandra DV 02 Mar '16

02 Mar '16

During very early boot-ROM execution the pinmux configuration isi in Hi-Z state. If pull-up is enabled on GPIO pad's there will be a short period of toggle from high to low on the IO when GPIO is set low during boot. To avoid this glitch, disable pull-up configuration in GPIO pinmux.

[U-Boot] [PATCH] serial: Move carriage return before line feed for some serial drivers

[U-Boot] placement for new clock drivers
by Dinh Nguyen 02 Mar '16

02 Mar '16

Hi, I have a few questions regarding the UCLASS_CLK driver. I need to implement a clock driver for a new-ish platform, an ARMv7 based SoCFPGA Arria10. I think going forward, it would make sense to place the driver to be of UCLASS_CLK and would go into drivers/clk/, instead of under arch/arm/mach-socfpga directory, Am I correct in assuming that? My 2nd question is regarding the usage of uclass_get_device(UCLASS_CLK). If I have a DTS that is from: arch/arm/dts/socfpga.dtsi Fragment of the clock portion from the DTS here: clkmgr@ffd04000 { compatible = "altr,clk-mgr"; reg = <0xffd04000 0x1000>; clocks { #address-cells = <1>; #size-cells = <0>; osc1: osc1 { #clock-cells = <0>; compatible = "fixed-clock"; clock-frequency = <25000000>; }; osc2: osc2 { #clock-cells = <0>; compatible = "fixed-clock"; }; f2s_periph_ref_clk: f2s_periph_ref_clk { #clock-cells = <0>; compatible = "fixed-clock"; }; f2s_sdram_ref_clk: f2s_sdram_ref_clk { #clock-cells = <0>; compatible = "fixed-clock"; }; }; I tried calling uclass_get_device(UCLASS_CLK, 0, dev), thinking that it would return the "fixed-clock" clocks, then I can get the frequencies and move forward with calculating the rest of the clocks. But uclass_get_device() is returning an error for me. I'm sure I might have missed understood how the clock framework is supposed to work somewhere. Can you please point me in the right direction? Thanks, Dinh

[U-Boot] [PATCH] usb: gadget: composite: Correct recovery path for register
by Semen Protsenko 01 Mar '16

01 Mar '16

From: Sam Protsenko <semen.protsenko(a)linaro.org> In case when usb_composite_register() failed once (for whatever reason), it will fail further even if all conditions are correct. Example: => fastboot 2 Invalid Controller Index couldn't find an available UDC g_dnl_register: failed!, error: -19 exit not allowed from main input shell. => fastboot 0 g_dnl_register: failed!, error: -22 exit not allowed from main input shell. Despite that 0 is correct index for USB controller, "fastboot 0" command will fail, because "composite" structure wasn't cleared properly on previous fail (on "fastboot 2" command). This patch fixes that erroneous behavior, allowing us to use composite even after previous failure.
