* treewide: replace #include <asm/errno.h> with <linux/errno.h>Masahiro Yamada2016-09-23-1/+1
| | | | | | | | | | | Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.

* imx: ventana: gsc: fix negative temperature readingsTim Harvey2016-05-31-0/+2
| | | | | | | The GSC Temperature sensor is a 2's complement value - adjust accordingly for negative temperatures. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
* imx: ventana: gsc: add gsc sleep commandTim Harvey2016-05-31-1/+45
| | | | | | | | | | | | The Gateworks System Controller on Ventana boards has the ability to disable the board's primary power supply until the RTC hits a specific time. When sleeping a button-down event on the GSC user pushbutton will wake the board before it's wake time has been reached. This feature is referred to as GSC sleep. Add a command to invoke sleep mode for a specified number of seconds. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
* imx: ventana: gsc: remove dependence on envTim Harvey2016-05-24-2/+2
| | | | | | remove dependence on getenv() by using global board info struct for model. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
* imx: ventana: move GSC boot watchdog disable function to gsc.cTim Harvey2015-05-15-0/+27
| | | | | | Move the code that disables the GSC boot watchdog into gsc.c Signed-off-by: Tim Harvey <tharvey@gateworks.com>
* imx: ventana: add 'gsc wd' command for enabling and disabling GSC watchdogTim Harvey2015-04-22-6/+74
| | | | | | | | | | | | | | | | | | This adds information about the Gateworks System Controller to the gsc command such as the firmware version, firmware CRC and status of the GSC watchdog (if its enabled and if its tripped). Additionally the 'gsc wd' command can be used to enable or disable the watchdog with the following usage: gsc wd enable [30|60] gsc wd disable Note that the GSC registers are battery-backed by the GSC coincell so once eanbled, they remain enabled across power-cycles or until either the GSC firmware has been updated or FLASH has been re-programmed by the Gateworks JTAG adapter.

* imx: ventana: gsc: add new hwmon railsTim Harvey2015-04-22-10/+9
| | | | | | | | | Add a new voltage rail added in various -C revision PCB's. Additionally make VDD_CORE, VDD_SOC, and VDD_IO2 common as all Ventana boards have those. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
* imx: ventana: remove GSC hwmon voltage rail min/max testTim Harvey2015-04-22-31/+22
| | | | | | | | The min/max of each depends not only on board but on CPU. Simplify by removing this rarely needed and difficult to maintain feature and just display the rails and their values. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
* imx: ventana: add GW5520 supportTim Harvey2014-09-09-0/+4
| | | | | | | | | | | The GW5520 has an IMX6Q SoC with 512MB of DDR3, 256MB of NAND flash as well as: * 2x MiniPCIe sockets * 2x USB host sockets * 2x i210 GigE * HDMI out * digital I/O expansion Signed-off-by: Tim Harvey <tharvey@gateworks.com>
* imx: ventana: add appropriate delay following GSC i2c writeTim Harvey2014-08-20-1/+1
| | | | | | | The Gateworks System Controller EEPROM config is flash based. Add a delay following writes to avoid errors on back-to-back writes. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
* ventana: Add Gateworks Ventana family supportTim Harvey2014-03-12-0/+129
Gateworks Ventana is a product family based on the i.MX6. This patch adds support for all boards in the Ventana family. Where possible, data from the boards EEPROM is used to determine various details about the board at runtime. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
