Message-ID<q2uo1-8ca-3@gated-at.bofh.it>
This series finally continues on my previous Easter efforts (BTW:
thanks all for the feedback and all the patches thereof already having
been applied) and additionally to activating the STMPE811 touch
controller also fixes HDMI, power I2C and the wake-up key.

Message-ID<q2uo1-8ca-11@gated-at.bofh.it>
In reply to#1215416
Improve the comment about the THERMD_ALERT# pin which is the unlatched
I2C address pin of the LM95245 temperature sensor and therefore
requires disabling for now otherwise it won't get detected properly.

While at it also move that pin further down to have it alphabetically
sorted again.

Fix HDMI supplies (both regular VDD as well as PLL ones) being switched
by the TPS65911 PMIC's GPIO6 aka EN_VDD_HDMI by introducing two new
GPIO switched fixed regulators avdd_hdmi_pll_1v8_reg and
avdd_hdmi_3v3_reg.
