If anyone has any objections, please let me know. ------------------ From: Dmitry Baryshkov [ Upstream commit 07db10de262f4150e24fd631a7a6c428f7bf80c9 ] With the default PSCI suspend value for cluster idle state Lenovo Yoga C630 isn't stable enough. For example it might reset if display device isn't probed early enough. Drop the bit 0x4000 from the PSCI suspend value to make C630 work in stable way. The bit was found by expertimenting with the cluster idle PSCI value. Most likely it results in the less deep sleep and more energy beign spent in the suspend state, but it's better than the non-stable system behaviour.
