| Subject: ASoC: Intel: Skylake: Disable clock gating during firmware and library download |
| |
| From: Pardha Saradhi K <pardha.saradhi.kesapragada@intel.com> |
| |
| |
| [ Upstream commit d5cc0a1fcbb5ddbef9fdd4c4a978da3254ddbf37 ] |
| |
| During firmware and library download, sometimes it is observed that |
| firmware and library download is timed-out resulting into probe failure. |
| |
| This patch disables dynamic clock gating while firmware and library |
| download. |
