Adds initial support for the HP Chromebook 11. Cc: Vincent Palatin <vpalatin@xxxxxxxxxxxx> Cc: Doug Anderson <dianders@xxxxxxxxxxxx> Cc: Stephan van Schaik <stephan@xxxxxxxxxxxxxx> Signed-off-by: Andreas Färber <afaerber@xxxxxxx> --- v4 -> v5: * Dropped bogus USB3 regulator (Vincent Palatin, Tomasz Figa) * Fixed USB3503 reset GPIO (Tomasz Figa) * Introduced labels to use new referencing style consistently (Tomasz Figa) * Don't override dp_hpd, moved to pinctrl_0 instead (Tomasz Figa) * mmc_1: Added comment from Snow's mmc_3 (Tomasz Figa / Doug Anderson) * Override /codec samsung,mfc-{l,r} properties for alignment with Arndale * Use more GPIO_ACTIVE_* constants * Use IRQ_TYPE_* constants * Dropped s5m_ prefix for s5m8767 LDO regulator labels (max77686 is gone) * Labeled also all s5m8767 BUCK regulators v3 -> v4: * Fixed samsung,pin-function 1 -> 0 for dp-hpd-gpio * Replaced dp-hpd-gpio with existing dp_hpd, overriding it v2 -> v3: * Use GPIO_ACTIVE_{LOW,HIGH} (Doug Anderson) * Use symbolic KEY_POWER instead of comment * Moved hsic_reset to new USB3503 node's reset-gpios (Vincent Palatin) * Use dp_hpd_gpio for dp-controller (Doug Anderson, Ajay Kumar) * Override sd1_{clk,cmd,cd,bus4} pinctrl similar to Snow (Doug Anderson) * Added ec_irq pinctrl for cros_ec (Doug Anderson) * Reordered nodes to minimize diff against Snow (Doug Anderson) * Dropped obsolete mmc_2 override (Doug Anderson) * Added lid-switch node (Doug Anderson) * Added gpio-keys pinctrl (Doug Anderson) * Added bootargs to avoid empty /chosen node and to document console setting * Renamed s5m8767_pmic node to avoid underscore * Use new style for overriding inherited pinctrl nodes, too * Enable i2s0 node v1 -> v2: * Use label-based overriding/extension of nodes. (Doug Anderson) * Dropped tps65090 for now, until we know where to place it. * Dropped non-Spring nodes from -cros-common.dtsi rather than disabling them. * Enabled a missing MMC node for access to internal storage. * Dropped display-timings from dp-controller node.
