[ Upstream commit 2e2ee5a2db06c4b81315514b01d06fe5644342e9 ]
On some platforms, the TPM power is managed by firmware and therefore we don't need to stop the TPM on suspend when going to a light version of suspend such as S0ix ("freeze" suspend state). Add a chip flag, TPM_CHIP_FLAG_FIRMWARE_POWER_MANAGED, to indicate this so that certain platforms can probe for the usage of this light suspend and avoid touching the TPM state across suspend/resume.
Are the patches needed to support CR50 (which need this patch) going to be applied to v5.4.y as well ? If not, what is the purpose of applying this patch to v5.4.y ?
Thanks, Guenter
Thanks Guenter. I think not.
