v5 -> v6:
* Updated for mfc node label
* Reverted to dp-hpd-gpio node in pinctrl_0 (Doug Anderson)
* Fixed alphabetical order of sd1_* nodes (Doug Anderson)
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. (Ajay Kumar)
