ipq40xx: Remove kernel 4.14 support
This target was switched to kernel 4.19 more than 6 months ago in commit
f342ffd300da ("treewide: kernel: bump some targets to 4.19") and now
with kernel 5.4 support being added it gets harder to support kernel
4.14 in addition to kernel 4.19 and 5.4.

However, other devices like the Asus -RT-AC58U and Meraki MR33 work just fine. - -The issue stem from the fact that all higher CPU-Clocks -are achieved by switching the clock-parent to the P_DDRPLLAPSS -(ddrpllapss). Which is set by Qualcomm's proprietary bootcode -as part of the DDR calibration. - -For example, the FB4040 uses 256 MiB Nanya NT5CC128M16IP clocked -at round 533 MHz (ddrpllsdcc = 190285714 Hz). - -whereas the 128 MiB Nanya NT5CC64M16GP-DI in the ASUS RT-AC58U is -clocked at a slightly higher 537 MHz ( ddrpllsdcc = 192000000 Hz). - -This patch attempts to fix the issue by modifying -clk_cpu_div_round_rate(), clk_cpu_div_set_rate(), clk_cpu_div_recalc_rate() -to use a new qcom_find_freq_close() function, which returns the closest -matching frequency, instead of the next higher. This way, the SoC in -the FB4040 (with its max clock speed of 710.4 MHz) will no longer -try to overclock to 761 MHz. - -Fixes: d83dcacea18 ("clk: qcom: ipq4019: Add the apss cpu pll divider clock node") -Signed-off-by: Christian Lamparter <chunkeey@gmail.com> -Signed-off-by: John Crispin <john@phrozen.org> ---- - drivers/clk/qcom/gcc-ipq4019.c | 34 +++++++++++++++++++++++++++++++--- - 1 file changed, 31 insertions(+), 3 deletions(-) - ---- a/drivers/clk/qcom/gcc-ipq4019.c -+++ b/drivers/clk/qcom/gcc-ipq4019.c -@@ -1253,6 +1253,29 @@ static const struct clk_fepll_vco gcc_fe - .reg = 0x2f020, - }; - -+ -+const struct freq_tbl *qcom_find_freq_close(const struct freq_tbl *f, -+ unsigned long rate) -+{ -+ const struct freq_tbl *last = NULL; -+ -+ for ( ; f->freq; f++) { -+ if (rate == f->freq) -+ return f; -+ -+ if (f->freq > rate) { -+ if (!last || -+ (f->freq - rate) < (rate - last->freq)) -+ return f; -+ else -+ return last; -+ } -+ last = f; -+ } -+ -+ return last; -+} -+ - /* - * Round rate function for APSS CPU PLL Clock divider. - * It looks up the frequency table and returns the next higher frequency -@@ -1265,7 +1288,7 @@ static long clk_cpu_div_round_rate(struc - struct clk_hw *p_hw; - const struct freq_tbl *f; - -- f = qcom_find_freq(pll->freq_tbl, rate); -+ f = qcom_find_freq_close(pll->freq_tbl, rate); - if (!f) - return -EINVAL; - -@@ -1288,7 +1311,7 @@ static int clk_cpu_div_set_rate(struct c - u32 mask; - int ret; - -- f = qcom_find_freq(pll->freq_tbl, rate); -+ f = qcom_find_freq_close(pll->freq_tbl, rate); - if (!f) - return -EINVAL; - -@@ -1315,6 +1338,7 @@ static unsigned long - clk_cpu_div_recalc_rate(struct clk_hw *hw, - unsigned long parent_rate) - { -+ const struct freq_tbl *f; - struct clk_fepll *pll = to_clk_fepll(hw); - u32 cdiv, pre_div; - u64 rate; -@@ -1335,7 +1359,11 @@ clk_cpu_div_recalc_rate(struct clk_hw *h - rate = clk_fepll_vco_calc_rate(pll, parent_rate) * 2; - do_div(rate, pre_div); - -- return rate; -+ f = qcom_find_freq_close(pll->freq_tbl, rate); -+ if (!f) -+ return rate; -+ -+ return f->freq; - }; - - static const struct clk_ops clk_regmap_cpu_div_ops = { diff --git a/target/linux/ipq40xx/patches-4.14/082-ARM-dts-ipq4019-Add-TZ-and-SMEM-reserved-regions.patch b/target/linux/ipq40xx/patches-4.14/082-ARM-dts-ipq4019-Add-TZ-and-SMEM-reserved-regions.patch deleted file mode 100644 index 6a595d5ef6..0000000000 --- a/target/linux/ipq40xx/patches-4.14/082-ARM-dts-ipq4019-Add-TZ-and-SMEM-reserved-regions.patch +++ /dev/null @@ -1,88 +0,0 @@ -From fc566294610fa49e9d8c31c4ecc9c82f49b11f59 Mon Sep 17 00:00:00 2001 -From: Sven Eckelmann <sven.eckelmann@openmesh.com> -Date: Wed, 18 Apr 2018 09:10:44 +0200 -Subject: [PATCH] ARM: dts: ipq4019: Add TZ and SMEM reserved regions - -The QSEE (trustzone) is started on IPQ4019 before Linux is started. -According to QCA, it is placed in in the the memory region -0x87e80000-0x88000000 and must not be accessed directly.

The block mode is not working properly since no handling in - being done for OUT_BLOCK_WRITE_REQ and IN_BLOCK_READ_READ. -3. An i2c transfer can contain multiple message and QUP v2 - supports reconfiguration during run in which the mode should be same - for all the sub transfer. Currently the mode is being programmed - before every sub transfer which is functionally wrong. If one message - is less than FIFO length and other message is greater than FIFO - length, then transfers will fail. - -Because of above, i2c v2 transfers of size greater than 64 are failing -with following error message - - i2c_qup 78b6000.i2c: timeout for fifo out full - -To make block mode working properly and move to use the interrupts -instead of polling, major code reorganization is required. Following -are the major changes done in this patch - -1. Remove the polling of TX FIFO free space and RX FIFO available - bytes and move to interrupts completely. QUP has QUP_MX_OUTPUT_DONE, - QUP_MX_INPUT_DONE, OUT_BLOCK_WRITE_REQ and IN_BLOCK_READ_REQ - interrupts to handle FIFO’s properly so check all these interrupts. -2. Determine the mode for transfer before starting by checking - all the tx/rx data length in each message. The complete message can be - transferred either in DMA mode or Programmed IO by FIFO/Block mode. - in DMA mode, both tx and rx uses same mode but in PIO mode, the TX and - RX can be in different mode. -3. During write, For FIFO mode, TX FIFO can be directly written - without checking for FIFO space. For block mode, the QUP will generate - OUT_BLOCK_WRITE_REQ interrupt whenever it has block size of available - space. -4. During read, both TX and RX FIFO will be used. TX will be used - for writing tags and RX will be used for receiving the data. In QUP, - TX and RX can operate in separate mode so configure modes accordingly. -5. For read FIFO mode, wait for QUP_MX_INPUT_DONE interrupt which - will be generated after all the bytes have been copied in RX FIFO. For - read Block mode, QUP will generate IN_BLOCK_READ_REQ interrupts - whenever it has block size of available data. -6. Split the transfer in chunk of one QUP block size(256 bytes) - and schedule each block separately. QUP v2 supports reconfiguration - during run in which QUP can transfer multiple blocks without issuing a - stop events. -7. Port the SMBus block read support for new code changes. - -Signed-off-by: Abhishek Sahu <absahu@codeaurora.org> -Reviewed-by: Sricharan R <sricharan@codeaurora.org> -Signed-off-by: Wolfram Sang <wsa@the-dreams.de> ---- - drivers/i2c/busses/i2c-qup.c | 900 ++++++++++++++++++++--------------- - 1 file changed, 515 insertions(+), 385 deletions(-) - ---- a/drivers/i2c/busses/i2c-qup.c -+++ b/drivers/i2c/busses/i2c-qup.c -@@ -141,17 +141,40 @@ - #define DEFAULT_SRC_CLK 20000000 - - /* -+ * Max tags length (start, stop and maximum 2 bytes address) for each QUP -+ * data transfer -+ */ -+#define QUP_MAX_TAGS_LEN 4 -+/* Max data length for each DATARD tags */ -+#define RECV_MAX_DATA_LEN 254 -+/* TAG length for DATA READ in RX FIFO */ -+#define READ_RX_TAGS_LEN 2 -+ -+/* - * count: no of blocks - * pos: current block number - * tx_tag_len: tx tag length for current block - * rx_tag_len: rx tag length for current block - * data_len: remaining data length for current message -+ * cur_blk_len: data length for current block - * total_tx_len: total tx length including tag bytes for current QUP transfer - * total_rx_len: total rx length including tag bytes for current QUP transfer -+ * tx_fifo_data_pos: current byte number in TX FIFO word - * tx_fifo_free: number of free bytes in current QUP block write. -+ * rx_fifo_data_pos: current byte number in RX FIFO word - * fifo_available: number of available bytes in RX FIFO for current - * QUP block read -+ * tx_fifo_data: QUP TX FIFO write works on word basis (4 bytes).
