Subject[PATCH v2 5/6] gpu: host1x: Add Tegra186 support
Date
Add support for the implementation of Host1x present on the Tegra186.
The register space has been shuffled around a little bit, requiring
addition of some chip-specific code sections. Tegra186 also adds
several new features, most importantly the hypervisor, but those are
not yet supported with this commit.

+ *
+ * <x>_<y>_s(void) : Returns size of field <y> of register <x> in bits.
+ *
+ * <x>_<y>_f(u32 v) : Returns a value based on 'v' which has been shifted

+ * can be |'d with others to produce a full register value for
+ * register <x>.
+ *
+ * <x>_<y>_m(void) : Returns a mask for field <y> of register <x>. This

+ * to place it at field <y> of register <x>. This value can be |'d
+ * with others to produce a full register value for <x>.
+ *
+ * <x>_<y>_v(u32 r) : Returns the value of field <y> from a full register

+ * This value is suitable for direct comparison with other unshifted
+ * values appropriate for use in field <y> of register <x>.
