Subject: [PATCH v1 10/17] clk: tegra: Remove tegra_pmc_clk_init along with clk ids
Date:   Mon, 18 Nov 2019 22:50:27 -0800
Message-ID: <1574146234-3871-11-git-send-email-skomatineni@nvidia.com>
In-Reply-To: <1574146234-3871-1-git-send-email-skomatineni@nvidia.com>
References: <1574146234-3871-1-git-send-email-skomatineni@nvidia.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Current Tegra clock driver registers PMC clocks clk_out_1, clk_out_2,
clk_out_3 and blink output in tegra_pmc_init() which does direct Tegra
PMC access during clk_ops and these PMC register read and write access
will not happen when PMC is in secure mode.

Any direct PMC register access from non-secure world will not go
through and all the PMC clocks and blink control are done in Tegra PMC
driver with PMC as clock provider.

This patch removes tegra_pmc_clk_init along with corresponding clk ids
from Tegra clock driver.
