Hi All, I would like to drop this patch, as I posted another patch using shared array for resets[1]. [1] https://lore.kernel.org/linux-renesas-soc/20220209203411.22332-1-biju.das.jz@xxxxxxxxxxxxxx/T/#u Regards, Biju > Subject: [PATCH] clk: renesas: rzg2l-cpg: Add id to struct rzg2l_reset > > We now have the reset ID split between common and additional entries. > But the index is hidden inside the DEF_RST macro and this can create > compilation issue when we add a reset ID on the additional entry array. > > This patch adds id to struct rzg2l_reset, so that we can lookup an ID > entry in the reset table instead of just using the ID as the index. > > Signed-off-by: Biju Das <biju.das.jz@xxxxxxxxxxxxxx> > --- > drivers/clk/renesas/rzg2l-cpg.c | 17 +++++++++++++---- > drivers/clk/renesas/rzg2l-cpg.h | 7 +++++-- > 2 files changed, 18 insertions(+), 6 deletions(-) > > diff --git a/drivers/clk/renesas/rzg2l-cpg.c b/drivers/clk/renesas/rzg2l- > cpg.c index 8c0a6252c984..adb3353a419d 100644 > --- a/drivers/clk/renesas/rzg2l-cpg.c > +++ b/drivers/clk/renesas/rzg2l-cpg.c > @@ -760,13 +760,22 @@ static int rzg2l_cpg_reset_xlate(struct > reset_controller_dev *rcdev, > struct rzg2l_cpg_priv *priv = rcdev_to_priv(rcdev); > const struct rzg2l_cpg_info *info = priv->info; > unsigned int id = reset_spec->args[0]; > + unsigned int i; > + > + if (id >= rcdev->nr_resets) > + goto err; > > - if (id >= rcdev->nr_resets || !info->resets[id].off) { > - dev_err(rcdev->dev, "Invalid reset index %u\n", id); > - return -EINVAL; > + for (i = 0; i < rcdev->nr_resets; i++) { > + if (info->resets[i].id == id) > + break; > } > > - return id; > + if (info->resets[i].off) > + return i; > + > +err: > + dev_err(rcdev->dev, "Invalid reset index %u\n", id); > + return -EINVAL; > } > > static int rzg2l_cpg_reset_controller_register(struct rzg2l_cpg_priv > *priv) diff --git a/drivers/clk/renesas/rzg2l-cpg.h > b/drivers/clk/renesas/rzg2l-cpg.h index 92c88f42ca7f..fe2bcf9cce5d 100644 > --- a/drivers/clk/renesas/rzg2l-cpg.h > +++ b/drivers/clk/renesas/rzg2l-cpg.h > @@ -150,16 +150,19 @@ struct rzg2l_mod_clk { > * > * @off: register offset > * @bit: reset bit > + * @id: reset index > */ > struct rzg2l_reset { > u16 off; > u8 bit; > + u8 id; > }; > > #define DEF_RST(_id, _off, _bit) \ > - [_id] = { \ > + { \ > .off = (_off), \ > - .bit = (_bit) \ > + .bit = (_bit), \ > + .id = (_id) \ > } > > /** > -- > 2.17.1
