[ Upstream commit 11b752ac5a07cbfd95592fac5237a02f45662926 ] The following table shows the values of the 'halt_reg' and the 'enable_reg' fields from the pcie clocks defined in the current driver: clock halt_reg enable_reg gcc_pcie0_ahb_clk 0x75010 0x75010 gcc_pcie0_aux_clk 0x75014 0x75014 gcc_pcie0_axi_m_clk 0x75008 0x75008 gcc_pcie0_axi_s_bridge_clk 0x75048 0x75048 gcc_pcie0_axi_s_clk 0x7500c 0x7500c gcc_pcie0_pipe_clk 0x75018 0x75018 gcc_pcie1_ahb_clk 0x76010 0x76010 gcc_pcie1_aux_clk 0x76014 0x76014 gcc_pcie1_axi_m_clk 0x76008 0x76008 gcc_pcie1_axi_s_bridge_clk 0x76048 0x76048 gcc_pcie1_axi_s_clk 0x7600c 0x7600c gcc_pcie1_pipe_clk 8* 0x76018 Based on the table, it is quite likely that the pcie0 and the pci1 clocks are using the same register layout, however it seems that the value of the 'halt_reg' field in the 'gcc_pcie1_pipe_clk' clock is wrong. In the downstream driver [1], the same '0x76018' value is used for both the 'halt_reg' and for the 'enable_reg' fields of the 'gcc_pcie1_pipe_clk' clock. Update the current driver to use the same value used downstream as probably that is the correct value. 1. https://git.codelinaro.org/clo/qsdk/oss/kernel/linux-ipq-5.4/-/blob/NHSS.QSDK.12.4.r4/drivers/clk/qcom/gcc-ipq5018.c?ref_type=heads#L2316 Fixes: e3fdbef1bab8 ("clk: qcom: Add Global Clock controller (GCC) driver for IPQ5018") Signed-off-by: Gabor Juhos <j4g8y7@gmail.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Reviewed-by: Kathiravan Thirumoorthy <quic_kathirav@quicinc.com> Link: https://lore.kernel.org/r/20240225-gcc-ipq5018-register-fixes-v1-2-3c191404d9f0@gmail.com Signed-off-by: Bjorn Andersson <andersson@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
